Xbox 2 specs leaked?

The specs for the Xbox 2 have turned up on a Chinese bulletin board. You can't take these as gospel — they could easily be faked, or Microsoft could change them before it comes out a year from now — but it's supposed to have a 3.5GHz processor, 256MB of RAM, and a 500MHz graphics chip. Whether or not it'll have a built-in hard drive is listed as "not decided" on the leaked schematic. Since you know Microsoft isn't going to confirm or deny anything, it'll be a long while before we learn whether these specs are for real or not.

UPDATE: Looks like they're fake.
