4 1/2 Years is more than enough time for it to "realistically" come out this year. Any game that needs 5 1/2 years to be completed better stand up to the hype behind it. It's feasible that its release could be this November. In fact, it's quite possible. Just because they've chosen not to show a lot doesn't mean the game isn't extremely far into progression if not already completed. You people are acting like they've just been working on this game for the past few months and are saying the release date is in November. It's been 4 1/2 years. Maybe they don't want to release a lot of stuff on the game so they could keep the speculation about it to a minimum?
The window is just about closed as far as marketing for a November 2012 release. I would think they would drop a release date by now to get those pre-order numbers up if it was coming out in the next 3-4 months.
Yea, the game is probably done. Rockstar maybe just sitting on it, doing little tweaks, until they feel its time to drop. I wouldn't be surprised if they're simply waiting on Wii U.
If Rockstar announces no release date by mid-September, GTAV is DEFINITELY not dropping this year.
