October is a pretty special month for Grand Theft Auto. Rockstar Games announced Grand Theft Auto 5 on October 25, 2011. Meanwhile, Grand Theft Auto: Vice City will celebrate its 20th anniversary later this month. Based on these two facts alone, it's easy to guess why a lot of fans are speculating that Rockstar will drop more news about the next GTA game in a few weeks. However, one particular insider is basing his theory on facts — and not just pure opinion.

As @LegacyKillaHD points out, Take-Two Interactive has its next investor call scheduled for November 6. Because of this, they claim that a GTA 6 reveal will likely happen before then before asking fans to pay attention to "late October/early November. The same source also insists that Take-Two will have to discuss GTA 6 during the incoming investors' call, saying that the "investors may have some questions about the recent hack that Rockstar Games suffered."
The leaker is talking about the dozens of GTA 6 development videos that found their way online following a massive security breach over at Rockstar. The company later confirmed that the footage was legitimate. UK police have since captured the 17-year-old suspect, who has already pleaded "not guilty" to the charges.

It doesn't take an insider to know that Take-Two will need to field concerns from investors following the incident. Because this is public info, it's possible that Take-Two will try to ease their worries by revealing details about GTA 6. Since this might include information that they would've loved to keep private, Rockstar might as well reveal a teaser trailer for GTA 6 before the month ends. If nothing else, this would coincide with the recent leaks regarding the new UFO event in GTA Online.

Based on the development footage, GTA 6 won't be around for at least half a decade.

It's been difficult trying to piece together what's real about GTA 6 and what's not. At this point, it's pretty much confirmed that GTA 6 will be set in Vice City following the events of GTA 5 with at least one female protagonist.

Fingers crossed, we'll finally get official GTA 6 info soon.
