We’re just going to tell you right here, right now. It won’t have in-game XMB, so stop complaining. With that out of the way, Eric Lempel has stated on the Official PlayStation Blog that Firmware 2.01 will be making it’s way onto systems shortly.
He didn’t go into specifics, but mentioned that the update would "improve the stability" of your PS3. To the majority of you, this update will most likely be meaningless. However, to the minority, who’s systems have been crashing and burning ever since 2.00, this [i]should[/i] fix all your issues.
More news on the upcoming firmware update soon.
