The game release date has been confirmed and will be available for Xbox 360 and PS3,says Rockstar.
The game was originally going to be released in spring 2013,Rockstar apologised for the mistake
In the announcement they said, “We know this is about four months later than originally planned and we know that this short delay will come as a disappointment to many of you, but, trust us, it will be worth the extra time. GTAV is a massively ambitious and complex game and it simply needs a little more polish to be of the standard we and, more importantly, you require.”
There is no word about a PC or Wii U version,or the new PS4 and Xbox720.But,I hope they come out a E3.
