Will the Xbox 2 come with a hard drive or not?

There's been a ton of speculation that the unlike the current Xbox (pictured at right), the Xbox 2 was going to come without a hard drive. Well, not that you should read too much into this, but Microsoft just received a patent for a "gaming system (that) includes a hard disk drive for storing applications and other data". Doesn't mean they're going to necessarily use that in relation to the Xbox 2, but it kinda seems like a step backwards to get rid of the hard drive in the Xbox.
