Just had a very quick look round but couldn't find this news anywhere, sorry if it's already been post.
I've read over at IGN that there's a whole bunch of new hardward coming out in 2006.
One that I'd read about previously is the GPS peripheral. While it's obvious this will have the ability to act as a typcial Sat Nav system, Sony claim it will be used for gaming as well.
How the hell would that be used for gaming? They even go as far to say the name of the game it will be first implemented in!!
Oh and it looks like the next firmware update is imminent "a spring Network update".
