While HDMI-equipped Xbox 360 Premiums are already fast making their way out into the wild, it looks like Best Buy may have now inadvertently added some further confusion to the SKU situation with a listing for an “Xbox 360 Core System w/ HDMI.” Such a system would certainly be news to us but, as you can see above, the image for the system in question quite clearly shows a Premium box, which also happens to match the $349.99 price listed (previously confirmed as the price for the HDMI-equipped Premiums). Those willing to take their chances on the mystery system, however, can put in a pre-order now, with it apparently set to ship on September 1st.
