No. This is a retcon. The Phoenix designs will still exist, but the classics are back.
I wasn't referring to the Phoenix artwork/designs, but the actual Unseen artwork. In other words, is an Unseen BattleMaster, or Warhammer, or Shadow Hawk no longer a BattleMaster, Warhammer or Shadow Hawk?
It should be noted that you can still use whatever you want in your games, but this allows the 3025-era variants to be used in official events (Demo Team events, GenCon, tournaments, etc.) and pictured in art. It also allows CGL and IWM to produce and sell miniatures of those variants again.
Yeah, got that part, and agree it's a good thing. I'm just trying to clarify if the old Unseen artwork is still considered valid for some versions/production runs of the 'Mechs, just like we somehow have two different sets of artwork for, say, the
Cameron class battlecruiser, both of which are considered canon/valid.
