Edit: BTW, a search for "KH3", "KHIII", "Kingdom Hearts 3", and "Kingdom Hearts III" returns literally hundreds of topics dating back to 2008, when topics first started archiving, but has been a frequent question since before KH2's release in 2006. ("KH3" returns the largest number of topics, BTW, for anyone curious about those old topics.)
I'd respectfully suggest you try writing SE directly, MrToXiC, to let them know your wants. If it was me, I'd look for a sales or marketing contact at square-enix.com; sales makes the squeakiest wheel.

I'm getting to the point where I don't care anymore. I have never played the ones on the DS and other platforms(though I would love to), so in the next year or so if there's no news, I think I'll close the book on ever looking forward to it
I think of people starving, Do you think I care? Let them all die hungry, so I can breathe their air!!
IMO it's going multiplatform and will be on next generation consoles. I don't see any chance it comes out on PS3/360, got to be next gen at this point. If it's an exclusive, I'll buy the system it's for, but I can't see it being an exclusive. Too much money to be made putting it on multiple consoles.
