My take is the Square-Enix head honchos are waiting to see which Kingdom Hearts spinoff earns them more money - the DS version or the PSP version.
If its a draw, the smart thing would probably be to put it on DS and hope it sells really really well, or put it on PSP and Wii, with the hope that the western Wii audience laps it up and the PSP rpg audience buys a number of copies as well. Final Fantasy XIII has been in development for so long now that I'm hesitant to think they'd risk putting Kingdom Hearts 3 it on only one HD platform, because if FFXIII can't recoup all its costs as a PS3 or 360 exclusive, the same would likely be true for KH3.
