I don't have the link by it said one of the people who work for rockstar said they should be bringing a new trailer showing the characters and that it should be coming out about 2nd February if not later that month
I think grand theft auto five is going to be released in the summer 2012 because gta is rockstars biggest seller so they would want to get it out there as soon as possible so they have the money for other projects they will release in the future
