the ps3 is region free, any game from any region will play on any ps3. but it doesnt mean the ps3 wont be able to detect what region the disc is from, insomniac just took advantage of that feature. if it was region locked, that disc wouldnt work on your ps3. im pretty sure that if you put a u.s version of motorstorm in your ps3, the game would play like the u.s version, because my guess is that they never put region specifics in that disc.
