PlayStation Home patch 1.3 adds universal game launching ... kind of
No, this form of launching won't allow you to group up with friends in Home and jump into a game of your choosing as a single, conglomerated entity. Rather, it lets you ... well, launch your games without having to return to the XMB. It was a wise choice to cut the middle man out of the game-booting equation, but it seems for the "full" game launching experience, Sony's going to have to add that functionality one title at a time.
Also added in the update is an in-game camera, in-store item previewing, new categories of clothing, new emotes, new spaces, and whole lot more. Check out PlayStation.Blog for the full scoop on the update.
