Sony Computer Entertainment Europe today confirmed that Gran Turismo 4: Prologue Signature Edition, a sort of demo disc containing 46 challenges and 64 cars, will be released in Europe next month. It will be packed with an additional disc that features a "Making of Gran Turismo 4" movie and a message from Kazunori Yamauchi, the creator of Gran Turismo.
Sony Computer Entertainment America, on the other hand, had no comment regarding a possible North American release.
While on the topic of racers that aren't coming to America, Codemasters today announced Colin McRae Rally 2005 for a fall release. The Colin McRae series is an Xbox exclusive in America, and as such the PlayStation 2 version of the title will stay in Europe.
We hope to receive word of a North American release for Gran Turismo 4: Prologue Signature Edition at E3.
