Rumor: Gran Turismo 6 for PS3 this holiday [update: it's official]

Gran Turismo 6 will reportedly launch this holiday season for PlayStation 3, according to iafrica, which allegedly obtained a leaked press release.

There is currently a Gran Turismo event going on at the Silverstone Circuit in the UK, where attendees are learning more about the series and are being treated to "exciting announcements about its future." Yesterday, the Sony-managed gran-turismo.com website featured a product listing for the unannounced simulation.

Gran Turismo 6 has been in development since 2010 and a Sony executive stated in February the game would be out this year for PS3. As this is Gran Turismo we're talking about, release windows may mirror dates that are closer than they actually appear.

Update 1: As spotted by Digital Spy, Someone at Toyota Europe Product Communications has been a busy tweeter at today's Gran Turismo event. We'll let the tweets (after the break) speak for themselves.

Update 2: It's official.
