I watched the video from the unveiling conference Wednesday. It definitely looks promising. If they keep they're promises on what it will be able to do, then I think it has a real potential to be a winner.
My major concern is security over Sony's Cloud Service that it will be connecting to and hopefully the cost isn't going to be as high as the PS3 was when it first came out.
Now we just need to hear from Microsoft and what their plan is for the next generation.
