IGN writes:
"Sony has confirmed that European PlayStation 3 owners can get behind the wheel of Gran Turismo 5 Prologue toward the end of the year. This taste of Sony's first true next-gen GT is scheduled for release on both Blu-Ray and PlayStation Network.
While Prologue is heading to PSN, it won't be free like the previously released Gran Turismo demo and doesn't include damage modelling - unlike the Blu-ray version. However, both versions do include more than 40 cars, as well as offering the chance to go head-to-head with fellow speed freaks in 16-player online races"
