GTA IV Sequel This Year?

Shacknews reports that according to Game Informer's latest issue, that we might just see a GTA sequel this year. Here are the details:

"We're not talking about new DLC or a collection of previously available DLC, we're talking about a full retail game

We expect this title to follow the suit of previous GTAs and use a subtitle such as GTA: San Andreas, etc. Tokyo might be a possible setting for the game, but details are non-existent at this time."
