Nope. Rockstar is holding it hostage until the end of spring.

My money is on them fucking annoucing that shit next week at E3, possibly with a next-gen version of the game (unconfirmed) and story mode DLC (confirmed to be in the works in a old newswire post IIRC), and the heist DLC actually coming out the very last day of sping.

Basically, what we've been playing this entire time was a beta of the actual game which will be coming out for PS4/XBO/PC later this year
