TGS '07: Remote Play functionality expands significantly
At Kaz Hirai's keynote in Tokyo Game Show, the PlayStation Portable's Remote Play feature was demonstrated. Mainichi Demo was on display with "new PSP functionality" that allows you to turn on and off your PlayStation 3 system via Remote Play, something that wasn't possible with previous versions of the feature.
In the future multiple PSP systems will be able to connect as a hub, as seen in this slide. Remote Play is a strong focus for Sony+ gamers will play games, use the PSP as a second screen and more.
