"Browsing the Playstation forums, it is evident that PS3 users want
cross game chat, maybe some sort of XMB party system as well. Perhaps some
are impatient waiting for Home to fully mature & offer features gamers
actually want, that were promised to them oh so long ago. The competition supposedly
owns the patent to XGC, (cross game chat) which makes it hard for Sony to offer a similar service. Finding
proof of this on the internet is a frustrating task, any official
information is elusive at best."
