A good tip to always remember: If it's not on GTAV.net, it is most certainly a fake. That's why you didn't see the site publish all those other faked linkedin accounts or CVs that pointed to an October release, because they didn't have any truth to them. The same applies for all the other so called leaks, like the "Adrian" main character one.
Once any real information comes from the Game Informer preview, expect it to be up on GTAV.net soon thereafter.
This rumor has now been confirmed as a FAKE as well by Game Informer's Managing Editor Matt Bertz via twitter
