I truely think they are gonna double dip everything they did that was popular in 1/6 scale.
In their future big licences, i could imagine them grabbing both 1/4 and 1/6, just in order to cut EB off any chances, especially on the DC and Marvel stuff. So a big 1/4 Man of Steel Superman is likely.
So lets see what popular characters they will most certainly do.... Predators, Ironman, Jack Sparrow, T1 or T3 Arnie T-800, Aliens.
Its definetly something you probably already own in 1/6 already.
Oh and please sideshow, let them reuse your licence and issue a 1/4 Indy.....~
