Atari went bankrupt three years ago (which is why so many of its assets like Star Control went up for auction), and the guy who bought the actual company gutted the operations (I think they're down to like a dozen full-time staff) -- the company now basically exists to license the Atari name and the few IPs it still owns. Heck, it doesn't even actually develop those social and mobile games it sells; an outside contract company builds them, and then the Atari logo gets slapped on them. Even if they were that insane, they wouldn't have the internal resources to develop something like that unless they somehow managed to execute the most massive secret mass hiring ramp-up in human history.
I'd bet anything that this is going to be a white-labeled Steambox, preloaded with a whole bunch of 2600 games and some old PC games that they still own (one of the Rollercoaster Tycoons, maybe) with some retro detailing like the wood grain paneling.
