There you go.. seems as if Sony got tired of Team Bondi and their way of missing deadlines, all rumors ofcourss, and that they're no longer funding the project. It also says "Expect to see a long-awaited reveal via a big cover story next month." - which could be anything really. But it could also mean that the long awaited multiplat announcement is on the way.
BUT.. the same "source" to claim that Sony isn't funding the project any more, just 3 months ago said "definitely ain't coming to Xbox 360, the size of the game is an obstacle to this."
So one can only speculate at the moment, and wait for next months reveal.
