Another recent rumor circulating the Internet suggests that PlayStation Home may be losing it’s current region-locked areas. Currently, users from a particular region (e.g. US) must be invite to visit another region (e.g. Japan) from a friend, it also means you can only socialize and play games players from the same region – the new change would mean everyone is in the same place.
Of course, this is just a rumor at the moment so it may not even happen. But it sure would help people interact more with players from around the world.
