Xbox 360 Premium confirmed shipping with HDMI 

Microsoft has confirmed the addition of HDMI ports to all newly manufactured Xbox 360 premium consoles. "Yes, we are offering an HDMI port for Xbox 360 simply as another choice in Xbox 360 owners' games and entertainment experience," a Microsoft rep stated. "Retailers are gradually introducing HDMI-enabled Xbox 360s into the channel to meet demand."

 Regarding the possibility of an HDMI output on the $279.99 SKU, the Microsoft rep said, "We have not announced any plans to add HDMI to the Xbox 360 Core System." Microsoft would not reveal whether any other additions had been made to newly available Xbox 360 models, such as the inclusion of a 65nm process. "We are constantly updating the console's more than 1700 internal components and therefore will not comment on details of specific components or manufacturing processes," the rep added.
