Today will be a big update for PlayStation Home
as 1.3 will introduce a host of new features. One big thing is any game in your Blu-ray drive will be launchable within Home so you don't have to go to the menu system to play the game if you don't want to.
Preview items in 3D in the store will be available although I'll never use it because I'm one of those that will never buy anything in Home.
For those that love to emote or do actions, new ones will be added. My son will like this as he loves to see my Home avatar dance around.
There's also a few things more that will be released that I haven't touched on but you can see some videos and more details on the Sony Blog
. I just tried to login to Home and got a network error so maybe they're prepping for today's update.
