Update: Andrew Reiner has confirmed that the game brought by Rockstar was Red Dead Redemption, not a future iteration of Grand Theft Auto.
Andrew Reiner, editor of GameInformer magazine, has posted on his twitter feed news of a possible Grand Theft Auto V announcement.
In his tweet, he states that Rockstar visited the GI offices, the game Rockstar brought with them may 'have been Grand Theft Auto V.'
Until we get a confirmation from Rockstar or GameInformer, we should take this with a grain of salt. Andrew did not give any more details, such as consoles or any kind of official revealing.
