Halo 3 Xbox sports HDMI, but 20GB drive ... wha?

Although not tattooed on Peter Moore's bicep, the Halo 3 Xbox was one of the true highlights of the Microsoft press conference. The console currently has no street date nor price, but it does sport a 20GB hard drive and -- what's this, an HDMI port? Aren't those reserved for the 120GB Elite? Guess not.

So is HDMI being rolled out to all Xbox 360 consoles, or is Microsoft going to charge a premium for the new look sans 120GB hard drive? Of course you could always slap 120GB drive on there at $180, but you're too smart for that. Remember that hardware update are "commonplace" in the industry.
