Guess I should have posted it here, but it completely slipped my mind. I ordered one on Saturday using this very method (5% off coupon), no tax, free shipping, excellent. It's still showing as "Sent to Warehouse", which is Buy.com-speak for "we've charged your credit card but it hasn't been shipped yet".
To clear up any HDMI/cable confusion: this is the normal package that everyone else carries, and does NOT include the HDMI cable (if you scroll down far enough, under "Features" there's a solitary bullet that says it's not included. What they mean when they list "HDMI" in the description is that this is the one that has the HDMI port available (earlier versions did not supply this port). The cable that's included is the HD AV cable with the 3-RCA component video connections (as opposed to the also-available S-video cable, which obviously only provides an SD signal), not the HDMI AV cable.
AFAIK, the inclusion of the HDMI port on the versions they named "Premium" came before the rollout of the Falcon 65nm processors (said to reduce heat and therefore RROD - though the jury is still out due to indications that only the CPU went to 65nm, while the GPU stayed 90nm), so the inclusion of the HDMI port should in no way be used to identify whether or not it's a Falcon.
I'll try and remember to post back the details of my unit when it arrives (though if it hasn't shipped by now, it probably won't make the weekend - dammit!). That is, if I'm not already neck-deep in Mass Effect, unable to extricate myself because the fate of the galaxy hangs on my every action.
