If Hasbro's got half a brain, the Vader will indeed be the same one from the next-to-impossible to find MOTDS 2-pack - ala the single carded MOTDS Maul already announced. It's the ANH version of Vader, and a very nice one at that. If Hasbro stuck with figures of this nature - VHTF stuff that was one of the better figure versions (Commtech R2, Stormie, Leia, Ep.1 later waves), the repacks wouldn't be such a big deal. In fact they'd be highly anticipated and appreciated.
And yes, I realize that whole need to keep some of the main characters "fresh" at the retail pegs, which I can live with. But at least pick some that aren't STILL at retail, like that damned KE Jango! What's up with that?!?
