During a demonstration at the Tokyo Game Show 2007, Kaz Hirai revealed that the PS3 and PSP’s Remote Play functionality has been updated so that you’ll be able to switch on, and switch off, your PS3 from anywhere in the world.
This will allow you to access you pictures, music and videos without having to leave your PlayStation 3 on.
The feature will be extended further to allow up to 3 PSP owners to play football/soccer on a host PS3. Also, another two PS3s could be used to spectate the match.
Stay tuned.
