Siccome gia in molti lo hanno chiesto,ecco quale è stata la risposta di Sony in merito
Sony has recently announced that its upcoming Sony PSP (PlayStation Portable) will not include Region blocking software.
Sony following on the footsteps of Game Boy Advance has decided keep its PSP region free. This move is in accordance to the nature of portable devices. Portable devices implicitly mean 'Portability', thus having region codes strapped on to game discs does not make sense, since people are expected to carry their systems with them on trips abroad and therefore be able to purchase software outside their native country or region.
Sony's PSP is based upon its new UMD (Universal Media Disc), a 60mm double-sided optical disc that can hold up to 1.8GB of data around 2 hours of high resolution full motion video playback at DVD quality. However, pressure from Hollywood means that movies distributed on UMD discs for the device will still have to be region locked (similar to DVD region locking).
Insomma il blocco regionale lo avranno solo i film in formato UMD,ma non i giochi![]()
