I feel like DDD is most probably getting remade into cutscenes (which, honestly, I don't mind... many gameplay elements were annoying). The thing is, there's too many touchscreen-exclusive features. It seems kind of hard to smoothy transfer features like training dream eaters, using reality shifts, or playing flick rush to the PS3. If anything, they *MIGHT* try to make a remake for PS4, since the controller has the touchpad, but I highly doubt it since the 3DS's touchscreen had video showing what you were slicing (reality shifts, mainly).
Also, there's still the whole 3D thing. Yes, they could just say this was for "Dream Drop Distance," but that seems stupid IMO, and I'd think most people would relate 3D to actually being 3D. Anyway, not everybody has a 3D TV, not to mention 3D TVs seem annoying: like, they can't get 3D right like the 3DS did.
I mainly loved KH3D for it's cutscenes anyway. Sure, flowmotion was amazing, but the entirety of The World That Never Was was freaking god-tier. Not to mention the composers pretty much went all out on the music, so most cutscenes were amazing anyway (From Tron dying to pretty much anything in Sora's side of Country of the Musketeers). It would be a shame not being able to fight to some of the battle themes, though, I have to admit.
