This is only the 2nd time I've heard about wanting KH3D remade for consoles so..
BbS was released in 2010, it'll be coming out for PS3 4 years later. Re:Coded released in 2011, it'll be coming out for PS3 3 years later *albeit in cutscene form*.
Nomura is hoping for a KH game every year right? Let's say KH3 isn't ready by 2015, what better game to fill in that spot than a KH3D remaster/make? By then the game will have been old enough for a PS3 update.
I guess what I'm saying is, I don't see the big deal? I mean unless it gets to unbearable whining levels *that I see with my own eyes* IDGAF.
