It depends on how quickly they resolve any issues regarding the new hardware and technology if you ask me. After that, it's simply a matter of porting and redesigning portions of the game.Uh, my bad, sorry. d^.^
Personally, it would work, but wouldn't reworking a game like DDD for the PS4 and Kingdom Shader be too much of a project? I dunno, but leaving that argument aside, yeah, DDD with KH3 would work, it's the game right before it, remastered beautifully.
I think this is very possible. It was about 2 1/2 years between COM and RECOM.
