Grand Theft Auto V is getting an update tomorrow and it's still not the Heists update.
The update we are getting tomorrow is the San Andreas Flight School update for GTA Online. It adds a bunch of new vehicles, both air and land, aerial solo challenges, and other things that Rockstar hasn't disclosed yet (how about Heists?).
The update will also change-up GTA Online gameplay. Payouts will be increased for the harder missions and you'll get more GTA$ for playing with others.
Expect more details on this update tomorrow, for now enjoy the Flight School video.
Have you given up on Heists in GTA Online? Let me know.
