Many games already support PlayStation Home, including Warhawk once the new patch becomes available to download. We all know that Home is scheduled to be released sometime this spring, but the release date could be earlier than first anticipated. According to a "insider", PlayStation Home will be available "very very soon". Sony already seems to be prepping an update to include in-game XMB access so Home could be part of that. But at this stage, this is considered a rumor until we official word from Sony.
According to the "insider":
"A game must be able to integrate into Home, a game must support ‘Accomplishments’. Right there, two important things, the PS3 system for achievements is called ‘Accomplishments’, and Home is coming out VERY VERY VERY Soon."
