When do you think Rockstar will officially release a teaser?

I think they will reveal something this November. Rockstar revealed GTA 5 for the first time out of nowhere in November 2011 so I'm thinking they'll do the same thing.

I would like to see something for GTA V's 10th Anniversary this week but chances are they'll just give out a new t-shirt and 1.05x job bonus or something.

Most likely that will be the case. It would be cool to see some type of big event in the game to celebrate the 10th anniversary.
