SCEE will be holding a invite-only press event on May 6th, and are expected to reveal the answers to a lot of questions. XTREME PS3 speculates that the PlayStation Home release schedule will be announced at the event. SCEE will be releasing multiple press releases after the event so look for those.
XTREME PS3 have received another email from an anonymous source stating the Media Event is "strictly press and developers, and press badges are being sent out." Further more, the event "will be similar to the Sony Gamers Day hosted last year."
