You've got to remember that most of the Unseen/Reseen have been
Classic'ed. That also includes the Dougram and Crusher Joe Mechs. Also apparently not all the Unseen/Reseen got done this time. Shimmering Sword, in a reply to a question in the
Ostscout's feedback area, mentions he didn't do a
Ostroc or
Ostsol in this first batch of
Classics.
And IIRC, there were only two Macross-Inspired Mechs between 1SW and 2SW's TROs: the
Valkyrie and
Wasp. Everything else was non-Macross Unseen/Reseen.
And to be clear, I believe Wrangler was talking about
Technical Readout: Succession Wars, not the mini-TROs that were in 1SW & 2SW. As to
if we see historicals on 3 & 4 SW, that'll depend on the new guys in charge.
