Various early reports (such as IGN) following the PS3's unveiling at E3 are saying that Sony have mentioned the next GTA could/will be a launch title. This hasn't been officially confirmed to my knowledge, but I did find this quote lurking amongst a bunch of other quotes from random developers regarding the new console:
|"Each time SCEI launches a console, the video games business moves to the next level. With PlayStation 3 it looks as if it might be time for interactive entertainment to become, finally, the world's dominant artistic medium." -- Sam Houser, President, Rockstar Games|
Not an official word on GTA's fate by any means, but if R* thinks the console is so grand, then why wouldn't they take the series there?
