"I know you've been complaining....but you weren't ready."

Yep - GTA Online's heists feature is FINALLY coming, long after it was initially promised. It will allow you and your crew (of real people!) to pull off crazy heists in Los Santos, separate from the single player game.

Per Rockstar:

GTA Online Heists are coming early in 2015 - check out the new trailer for the four-player co-op mode for Grand Theft Auto Online that allows players to plan, prepare and execute multi-tiered Heists across Los Santos and Blaine County. These will require tight communication and coordination, with players taking on specified roles at each point to accomplish multiple objectives on the way to each Heist's epic finale. Featuring new gameplay, new vehicles, new weapons, new clothing and much more.

Of course, there's still that caveat - "Early in 2015" isn't a very specific date, but it seems believable that they wouldn't bother announcing it like this if they weren't certain it was legitimately on its way very soon.

But as soon as it does, I AM SO ROBBING AN AIRCRAFT CARRIER.
