One of the most attractive promised features of PlayStation Home was the ability to meet up with friends in Sony's virtual space, pick a PS3 title and join in the multiplayer offerings of said title as a group. Sony's delivered on that promise by adding this functionality for a few select titles, such as MotorStorm and Street Fighter IV. However, these capabilities are going "universal" with the release of Home Patch 1.3, which will add "simplified game launching" to the service.
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.
