Outside of the DualShock 3, SCE chief Kazuo Hirai made a few minor announcements regarding Sony's progress in the networking field in is keynote address this morning at the Tokyo Game Show.

In a disappointing note, Hirai revealed that the PlayStation Home platform for the PS3 has been delayed into a new target of Spring 2008. No details were made available.

However, Hirai did outline a few items regarding the PSP. Powering PlayStation 3 systems on and off while on the go will soon be possible under the PSP's Remote Play functionality. In addition, multiple PSPs will now be able to connect to a single PS3.

Hirai used an example of a golf game to illustrate: "For example if you're playing a golf game, your friends can connect through the PSP as spectators. There is also the possibility for combining the data transfer functionality through the PSP so you'll be able to send certain games that you've been playing on the PS3 and transfer them to your PSP so you can continue playing."
