PS3 games are regionfree, you have to have HDTV to use EU PS3 games on a US PS3 cause it refuses to output PAL
BluRay will be locked to region A(but all movies from Paramount, Warner and Universal are region free)
DVD is locked to Region 1
and lastly PS3 has a powersupply that supports 110-240V. I can confrim this because i live in Europe and have an US PS3
