BTW, here is
RebelScum's rumor list for after Hoth:
Jedi Masters -- I'm guessing it's Mace, Saesee, Agen Kolar, and Kit Fisto from the Palpy office confrontation.
New Empire-- not sure what this would be.
The Star Destroyer bridge at the end? Palpy, Vader, Tarkin, & generic officer? That would be nifty, but I really don't see them going this obscure so early in the line.
Maybe just some ROTS clonetroopers in plain white armor, with a generic Imperial officer.
Or, if we take it as a literal reference to "my new empire", maybe it's Obi, Mustafar Padme, pre-crispy Vader, and .... what, 3PO?
Vader's (501st) Legion
Shocktroopers
