Really? The gaming community has shown nothing but contempt for the months of silence from Playstation, and then when they finally start talking, it's that disastrous Mark Cerny thing that was being ridiculed from most quarters.
Xbox has been releasing small amounts of information for a while now too. It's just how they've decided to do things this gen it seems.
One thing we can definitely say is that Sony know what they're doing in terms of releasing information. The way they're releasing information in small amounts has everyone paying attention whenever they're doing it.
