Thanks to everyone for the updates from their respective locales. The stores around me seem to be at least a few weeks behind the bleeding edge that some of you guys are finding.

Mind throwing me a link. The search isn't working for me and i'm looking in the "All Cases/Cooling/PSUs Articles" which keeps giving me errors.
Link is in the first post. It's also under the "gadgets" tab from the AT front page.
To those wondering about the 80nm GPU : this is based on Anand measuring the Xenon/Zephyr GPU die and comparing it to Falcon GPU die. The Falcon appeared to be smaller, but not small enough to be 65nm. It was consistent with an 80nm half-node shrink, which is an optical shrink that doesn't require a redesign like a "true" process shrink (to 65nm for example). There's nothing confirmed from Microsoft. Then again, they never discuss these sorts of things.
Microsoft purchased the design of the GPU from ATI/AMD, so they own the full rights to the IP. I believe, but am not sure, that MS did all the chip layout work on the original design. There are
rumors that MS was going to contract out future chip design work after they had so much trouble with the 90nm design. It's unclear, however, if that was for the 80nm optical shrink or the theoretical 65 or 55nm Jasper GPU. It could even be related to the next gen Xbox, but I think that's less likely.
