You know, a lot of those rumors that have been swirling around about the Cafe may have really been about this new Microsoft console instead.
ETA: This also is going to add even more pressure on Sony to put out a PS4. They already have plenty of pressure with the PS3 being hopelessly and permanently hacked wide open, but now with both competitors putting out systems which presumably leave the PS3 in the dust (technologically speaking), there is now an even much greater urgency. The thing is though, I don't think Sony will be able to get their next console out quite as fast, but you can bet they are going to move much quicker now than they otherwise would have.
