Didn't see any posts but it looks like the Xbone S is out already. Not much point with them having already announced Scorpio coming soon. Might be worth it if you really wanted the drive right now though.
They've fixed their (misleading?) advertising for it. Gives you an idea of actual the size difference.
Actual:
Original announcement with the wrong information.
EDIT: Forgot that the 2TB version is apparently a "limited edition" version. The standard 500 GB and 1TB isn't limited though.
