Damn I thought the update was out already...grrrrrrrr
Anyway, everyone is touting that the next firmware update is 2.40 and will include in-game XMB, something the Xbox 360 currently has where you can send messages via while playing games and listen to music while in-game.
So in-game XMB and the new Trophies system that is suppose to be similar to the Xbox 360 achievement system.
Hopefully this rumored update is true :)
