My money is on a reissue of the TRU Hunt For Grievous pack from last year.
Thatd actually be extremely cool, because I missed out on that set.
But, if something original were to be released, I'd like to see:
Evo Anakin w/Sith eyes
Order 66 2Pack Commander Bow
and 3x pauldronless Appo
That would be the best BP ever!
Another cool idea but something Hasbro would never give us is:
Swimtime Kit Fisto (from Final 22)
and 4x Clone Scuba Troopers
(But that idea'll never happen
Anyway, make it good, Hasbro.
