Believe it or not, it has been over 15 years since Gran Turismo debuted. And now it's time to celebrate.

Polyphony Digital and Sony are paying homage to what many consider to be the greatest video game racing franchise of all time. As revealed over at the PlayStation Blog , there will be a special Gran Turismo 15th Anniversary Event at the Silverstone Race Circuit in England on May 15. It's a fitting setting, yes?

And at that event, series creator Kazunori Yamauchi will make "some exciting announcements about the future of the brand." If you're intrigued, you can follow the activities at the Blog, or at GranTurismo.com . For months, we've been anticipating the unveiling of Gran Turismo 6 , which could be a cross-generation title. We've seen evidence of it coming to the PS3, but none that would indicate it might arrive on the PS4…maybe that's part of the "exciting announcements" on tap, though. GT6 as a PS4 launch title!

Who's ready for more Gran Turismo ?
