Sony has a similar policy for the PlayStation Portable, but most publishers choose not to encode a region on their UMD games. With the exception of Persona 4 Arena, PlayStation 3 Blu-ray Disc games are region-free. The PlayStation 4 and Xbox One are completely region free, allowing usage in all standards regions, although the Xbox One was originally going to have region locking before changing this due to consumer outcry.[1] All Nintendo home consoles except for the Nintendo Switch have region locking either by software encoding or physical differences in media and consoles.
