You'd expect cooler, new 65nm chips dubbed “Falcon” to lurk within the new HDMI version of Xbox 360, wouldn't you? But it’s not to be, at least not yet.

According to a Neogaf forum user that goes by the name of Wonderkins, the new Xbox 360 Premium has only the old “Zephyr” chipset. The new quieter BenQ DVD ROM drive is a nice plus but you’ll have to wait on the cooler chips.

Speculation from Wonderkins is that this early run of HDMI Xbox 360s doesn’t include the Falcon chip yet, but later runs will. Here at GizmoCafe, we're hopeful that Falcon will make an appearance soon. Wonderkins suggests you check the multi-barcode sticker on the side of your Xbox 360. Make sure it’s the HDMI version and if it’s lot 0727, it’s not going to include the 65nm chipsets. Wonderkins says it’s possible that subsequent lot numbers (i.e., lot 0728, and onward) will include the new cooler chipsets.

If you’re on the hunt for your new and improved Xbox 360, good luck and I’ll continue to scour the web for more clues.
