While I personally don't give a damn about a possible new console, the speculation on Atariage pretty much sums up what's publically-known about it, which at this point is next to nothing.
Assuming it's not a hoax or vapourware (yes, I know about the guy who was part of the focus group), it's difficult to really care. Atari is long dead, and trying to compete in today's console market is basically suicide unless you have the capital and operational resources of Apple, Google, Amazon, or similar.
