Beatles, IF (a big if) they do it right and focus on the Revolver/Magical Mystery Tour/Sgt. Pepper’s era. If it emphasizes the whimsical, psychedelic stuff and has Zombi Yeti or Dirty Donnie doing the art, it could be a home run if it shoots well and has good rules/code.
I sort of feel as if Iron Maiden is beyond “rumoured” at this point, but that would be the other one.
The CGC remakes are going to be great too, but lately I find myself getting a lot more excited about all the new stuff coming out.
