Bad for Sony when it comes to price. Even if they don't announce a price MS can get a good feel as to how much they would charge. Would put MS in place to take losses on the console by going cheaper if need be.
Could potentially be very bad for Sony if they reveal too much in terms of secrets/features that MS could copy in short term like the supposed video sharing and what not.
Everything else? Positive, positive, positive for Sony as long as they show everything right. The ball is in Sony's hands.
It's just that simple.
