Esto esta sacado de la pagina de price japan, creo que pone que no son compatibles los juegos PAL no? esto seria una seria razon para no comprar una ps3 japonesa:
Are PS3 games region-locked?
Nope, well, neither NTSC-J or NTSC-U games are. Both boot fine on either a Japanese or American machine. Rumour suggests however, that European games won't work on an NTSC machine and vice versa.
Y tambien dice algo de los blue-ray, pone algo de la region, tampoco seran compatibles nuestros blu-ray, tambien sacado de price japan:
Okay, I wanna watch some of these new Blu-ray films, what's the deal?
Rightio, unlike Toshiba's region-free HD-DVD's, Blu-ray does make use of region-coding. Both Japanese and American PS3's share the same region (A1), therefore American Blu-ray DVD's will work quite happily on a Japanese machine and vice versa.
Here's a brief breakdown of the Blu-ray Regions;
A1 - North America, Central America, South America, Korea, Japan and South East Asia.
B2 - Europe, Greenland, French territories, Middle East, Africa, Australia and New Zealand.
C3 - China, Russia, Central and South Asia.
So, will American Blu-ray DVD's work on my PAL PS3?
Obviously, it can't be confirmed at the moment, but all signs point to no, sadly.
