The development team at Polyphony Digital and publisher Sony might be getting ready to reveal Gran Turismo 6 as part of an event that is set to celebrate 15 years since the racing game was first launched.
The two companies are holding a celebration at the Silverstone circuit on May 15.
The official invitation, obtained by users on NeoGAF, reads: “Join Us to Celebrate 15 Years of Gran Turismo, and discover the exciting announcements about its future.”
Listings for Gran Turismo 6 have already appeared on two retailer websites, with launch dates set for late this year.
The racing game series is known for the quality of its simulation engine and traditionally, a Gran Turismo title has been used by Sony to show off the power of its home consoles.
The PlayStation 4 is also set to launch before the end of the year.
