A while back Sony announced they would unveil the PS3 at a briefing held in Japan sometime during the month of March. As you can tell, today is the end of March and late last night Sony sent out word that this unveiling wasn’t going to happen. Sony left the door open for a possible Pre-E3 event, but said E3 would be the latest it would wait to show off the new console.
Sony says the event was cancelled to avoid pressuring developers. I am not sure how showing off the new console will pressure them, but whatever. Expect to see Sony go big on this unveiling.
