The Tiger "Citadel" does not say "new parts" therefore it will probably be their old Tiger early perhaps with the updated turret sprues of their mid and late kits. So no new parts made for this boxing but new parts that weren't in previous releases.
The M163 and Zelda don't say new parts either so there is no reason to expect any. Reading comprehension and critical thinking skills people. What does the document actually say? Not "what do I want it to say"

I would love it to say M981 reissue with new parts to make a M901. But it doesn't.

But we will be getting another entrant into the King Tiger sweepstakes. Academy will be adding new parts to their KT probably to make an earlier production version and if their Tiger I middle is any indication it might include Zimmerit decals? Yippee! I am so ooo under-whelmed and full of cynicism!
By the way this is the entire page listing service for armor by Academy. If you don't see it, it does not exist as of the date of publication.
