Last week, Rockstar Games released its Beach Bum DLC update and also teased some new additions to Grand Theft Auto Online. Bloggers and gamers are now speculating as to what these updates may be.

"This is just the first of many new content updates we're working on for Grand Theft Auto Online in the weeks and months ahead ... [including] Content Creator, full on cooperative Heists, and GTA Online's take on Capture the Flag ... [and] new Story Mode updates as well," Rockstar Games said when it announced the release of the Beach Bum update.

One rumor is that a downloadable casino heist mission will soon be available to Los Santos' car thieves. The possibility is a popular one on gaming forums. Speculators created the theory after considering a mysterious "Opening Soon" sign which sits in front of the in-game casino that is already present in Los Santos.

Rockstar Games has yet to deny or confirm the casino heist rumor.

Another theory, on the other hand, has already been debunked.

"For a time, the most likely answer was a new set of missions set in North Yankton (the remote, snowy area in which the missions 'Prologue' and 'Bury the Hatchet' are set)," The Independent, a British newspaper, said. "However, this rumour has since lost all credibility, with the person behind it admitting they made it up."

The Beach Bum update will be released tomorrow, Nov. 19. It includes new beach-themed jobs, vehicles, weapons and customization options.

 "All the new Beach Bum content will be added automatically to GTA Online through our next title update (1.06), and will include two new weapons, a quartet of rugged and fun new vehicles for land and sea, lots of new action-packed Jobs, plus a wide variety of suitably rad new apparel, hairstyle and tattoo customization options," Rockstar said via its Newswire page.
