The Xbox 360 Elite package has it. The upcoming very, very special Halo Edtion Xbox 360 package will have it. Hell, why not put it on everything else!
Aside from the 360 upgrade chip gossip roaming around, the tech gurus over at Ars Technica said that 'a new version of the Core and Premium (Xbox 360) in late August and September...will include an HDMI port,' according to their 'inside source'. Microsoft has been very hush with rumors: Price-cuts, chip upgrades, and now this. But from the looks of how things have been going in the 360 rumor circle, it looks like this one's bound to happen.
An upgraded chip plus an HDMI port sounds like a great console to us-except for that forsaken 'ring of death'. It would simply equal an epic holiday console showdown: Should you go buy a Blu-Ray enabled PS3? Or battle it online with Super Smash Bros. Brawl on the Wii? Maybe just dive in to the (eventually) improved 360? So many choices...so little bank accounts.
