Not sure what your question is here, Wellard.
In canon, as per 3067 the mechs which comprise the "unseen" are no longer being produced in the "unseen" form. New manufacture, and significant upgrades, are done in "reseen" form. So TRO 3085 correctly shows what you'd expect to see those designs looking like in 3085 - in the Project Phoenix versions.
That doesn't mean there aren't some older designs still knocking about, in backwater militias, periphery kingdoms, or as-yet undiscovered star-league era caches. But most militaries have either scrapped the old versions, or upgraded them to the new specs over time.
Now I notice that you've also posted an item about the Palladium Robotech minis. Anticipating a few questions:
1) You're free to buy Robotech minis for use in your own Battletech games, in the same way you're free to buy CAV, Mekton, MechWarrior:Dark Age or other minis for use in your own games. You can kitbash, sculpt or gnaw from soap your own minis for use in your own games.
2) BattleTech will never again be using art from or directly inspired by external sources related to Macross, Robotech, or any of the related incarnations of that product - or pretty much any other external source not controlled by Topps or CGL. The copyright issues just aren't worth getting involved in again.
3) Catalyst Game Labs will not be using miniatures classed as "unseen" in any official games or events.
4) You'll be welcome to post pictures of minis made for Palladium's Robotech game. The only minis we don't allow to be shown are illegal reproductions - that includes recasts of someone else's work, or derivatives of someone else's IP made without permission of the copyright holders.
Hope that helps,
W.
