I think that PS3 box is jumping the gun on itself. Also KH3 has nothing to do with the keyblade wars. Those already happened in the past.
If its current gen, the game should come out on PS3/360/Wii U. Not likely in my opinion as the team has to finish versus13 first.
Theres also the possibility that it becomes a Wii U exclusive (oh noes PS fanboys will make a riot again/who cares about them). Likely in my opinion as the system gains a foothold in Japan.
And finally the possibility that it comes out on PS4/Wii U as next gen. Also likely that instead of an exclusive they try to support both japanese systems.
I am pretty much convinced it will come out for the Wii U. KH games have had spin-offs in the nintendo handhelds and its looking like the Wii U might dominate the japanese market. Even though the series seems to sell more in the US, i dont think the developers care.
And, it will likely have a star wars world if it comes out after 2014.
