Two days ago we reported that Sony had some new game announcements coming up soon, and suggested that one of them may be related to Gran Turismo. A new trailer for the 15th Anniversary of the series was released today, further supporting the notion that more GT is on the way.
The trailer below is essentially a highlight reel for the franchise, but at the very end, some text ticks through every entry to the series starting with the first Gran Turismo. After the latest release, GT5, the cursor just keeps blinking, as to imply they're just waiting to type a big fat number 6 into that box.
With E3 around the corner, announcements coming this week, and a Gran Turismo 15th Anniversary event in Europe on May 15th, expect a new Gran Turismo game to be revealed very soon.
