So I was bored, and decided to break down how many units from each Technical Readout have been produced for the mass market (i.e., not the Premium miniatures) by Catalyst Game Labs since 2018's A Game of Armored Combat boxed set.
Technical Readout 2750: 13/20 'Mechs, nothing else. It's missing the Thorn, Hermes, Hussar, Wyvern, Kintaro, Champion, and Bombardier. The Kintaro is in the queue for a future ForcePack, and fans have suggested one more ComStar or Word of Blake Level II to cover the rest.
Technical Readout 3025: 55/55 'Mechs, 5/10 vehicles, 0/3 LAMs, 1/15 fighters, 2/4 DropShips. Aside from the LAMs, 3025 is 100% 'Mech complete.
Technical Readout 3025 Revised: 48/55 'Mechs, 5/10 vehicles, 1/15 fighters, 2/4 DropShips. This cut the Unseen and added in the 'Mechs from Tech Readout 2750; the missing 'Mechs are the same ones from that volume.
Technical Readout 3026: 21/35 vehicles, 0/4 conventional aircraft. Aside from TR3075's SM Tank Destroyer, every vehicle yet seen (or announced) comes from this and Tech Readout 3025.
Technical Readout 3026 Revised: 20/39 vehicles, nothing else. This cut a chapter of personal equipment and added in a number of units, none of which have been made in plastic so far. The Galleon Light Tank was cut and wouldn't reappear in its 3025-era guise until the Recognition Guide series.
Technical Readout 3039: 73/82 'Mechs, 26/48 vehicles, 1/17 aerospace fighters, 0/8 conventional fighters. This missing 'Mechs are from Tech Readout 2750 or the Wolf's Dragoons sourcebook.
Technical Readout 3050: 89/95 'Mechs and Elemental battle armor. It's missing two 'Mechs shared with 2750 (Hermes and Kintaro), plus the Hornet, Falcon, Wolf Trap, and Imp. A single Inner Sphere Lance ForcePack could cover the last four, but it'd be tricky to come up with a justification for it. The Wolf Trap was developed by the Combine during the "Death to Mercenaries" period, and the other three are all signature 'Mechs from Wolf's Dragoons.
Technical Readout 3050 Revised: 76/87 'Mechs, 0/18 vehicles. The missing 'Mechs are as from the original Tech 3050, plus the Hussar, Champion, and Bombardier.
Technical Readout 3050 Upgrade: 76/87 'Mechs, nothing else. Same notes as 3050 Revised.
Technical Readout 3055: 22/59 'Mechs, 1/12 fighters. It's only missing three Clan 'Mechs (Glass Spider, Phantom and Naga), but just four Inner Sphere 'Mechs from the book have been made so far.
Technical Readout 3055 Revised: 15/52 'Mechs, 1/12 fighters. This cut most of the IICs without replacing them with anything.
Technical Readout 3055 Upgrade: 15/80 'Mechs, 1/12 fighters. This edition kept the cuts from 3055 Revised, but added in the "Phoenix" versions of the Nexus, Raijin, and Grand Crusader (originally in Tech Readout 3058), plus a chapter on Solaris VII 'Mechs.
Technical Readout 3057: 2/47 aerospace fighters, 3/40 DropShips, nothing else.
Technical Readout 3057 Revised: 3/40 DropShips, nothing else. This cut the pages of fighter stats for more WarShips.
Technical Readout 3058: 29/55 'Mechs, 9/36 vehicles. Just one Clan 'Mech hasn't been made from this volume - the Thresher - but again, few Inner Sphere 'Mechs appear from it. All the vehicles produced so far are updates from Tech Readouts 3025 and 3026.
Technical Readout 3058 Upgrade: 29/51 'Mechs, 9/36 vehicles, 2/20 battle armor. The Nexus, Raijin, Grand Crusader, and Mackie were cut, but chapters on battle armor were added.
Technical Readout 3060: 5/56 'Mechs, nothing else. All five of these units are Clan 'Mechs.
Technical Readout 3067: 2/45 'Mechs, nothing else. One each Inner Sphere and Clan 'Mech.
Technical Readout 3075: 7/42 'Mechs, 1/28 vehicles, nothing else. Aside from the SM Tank Destroyer, these are all historical units, basically the six Inner Sphere 'Mechs from Proliferation Cycle plus the Atlas II.
Technical Readout 3085: Nothing yet.
Technical Readout 3085 Supplemental: Nothing yet.
Technical Readout 3145: Nothing yet.
Technical Readout 3150: 1/37 'Mechs, nothing else.
Recognition Guide 1: Classics: 41/45 'Mechs. The four missing units are the Glass Spider, Nexus, Raijin, and Grand Crusader.
Recognition Guide 2: ilClan: 118/152 'Mechs, 27/40 vehicles, 2/6 battle armor. The format of this book allows for far more units to be included than usual. The only brand-new unit from this volume is the Regent 'Mech.
Golden Century: 4/17 'Mechs, nothing else. Many of these are variants with new names, so I included them in the counts.
Irregulars: 2/19 IndustrialMechs, nothing else. The Firebee and Centurion MilitiaMechs are downgrades of standard 'Mechs, so I included them in the counts.
Project Phoenix: Nothing yet.
Prototypes: 8/25 'Mechs, 6/27 vehicles, 1/7 battle armor, nothing else. These almost all count as new variants of existing units, so are included in my counts. The Kalki, despite being based in-universe on the SturmFeur, is so radically different that I consider it a new unit. The Elemental II battle armor, on the other hand, is just a variant despite the Roman numeral (Recognition Guide 2's Elemental III armor bears this out).
Vehicle Annex: Nothing yet.
Vehicle Annex Revised: Nothing yet.
Succession Wars: 76/93 'Mechs. Most of the missing units are from Tech Readouts 2750 and 3050, plus a few more from 3075.
Clan Invasion: 46/93 'Mechs. Most of the Clan 'Mechs have been produced in plastic, but the vast majority of the Inner Sphere have not. Many IS units use the Phoenix art.
Jihad: 4/93 'Mechs. Again, several units use Phoenix art.
Dark Age: Nothing yet.
When the Star League Assault Lance hits proper distribution, it'll add one more unit each from Tech Readouts 3025 (coolant truck), 3058 (Emperor), 3060 (Helios), and 3067 (Argus). The McCarron's Armored Cavalry Assault lance will add one 'Mech from Tech Readout 3145 (Tian-Zong). There's over 100 more units in the tentative product schedule shown at KerenskyCon, so plenty of these "holes" will be filled over the next couple of years. I'll note new ForcePacks here as their contents are confirmed and they're entering distribution. Once they're in general release, I'll add them to the above lists.
P.S. - Note that I consider the Phoenix and MWDA redesigns to be unique models. In most cases, units that append Roman numerals (e.g., Mad Cat III or Marauder IIC) are considered to be new models, while variant designations (Atlas AS7-D vs. AS7-K, or Griffin IIC vs. Griffin IIC 3) are considered the same model unless they have new art from Phoenix/MWDA. LAMs, QuadVees, and IndustrialMechs are all their own types of unit, with a couple of noted exceptions.
