I'm just hoping the final round of Rec Guides will include the Shogun, because that looks like the only way we'll see record sheets for the 3E and C 2 anytime soon.
Except that non-Classic, extant Spheroid 'Mechs haven't gotten multiple variants, only one featured variant.
I would assume it would be extremely unlikely the Shogun would get a full entry, instead being relegated to a one-third entry and only one new variant.
Granted, that could be either the 3E or C 2, but the other would go unseen.
Of course, i suppose it is possible these mini-entries could get variants, but that seems unlikely.
I will note that the RGs have so mentioned few variants that didn't get record sheets (Stinger Cs, Wolfs Dragoons Stone Rhino from Misery, others?), so i'm guessing these might be reserved for a future product, or perhaps they will debut with compilation RG.
And there's always a chance the 3150NTNU and Prototypes unabridged will surface in some manner.
Somewhat related, i wonder if the Atlas will get a full entry or a one-third entry. It is iconic enough it could get a full entry, but at the same time it ain't a classic. But at least two modern Atlas variants have been hinted at: a Kuritan upgrade with Ballistic-Reinforced armor (Marauder II entry) and a C 2-model from BattleTech Legends.
