Well it seems Best Buy got their Xbox 360 demo unit in, and set it up yesterday (Sat) at some point. Well per my other post Wal-mart employees evidently don't know how to set up an HD tv, because the one at Best Buy looked soooo much better! I was still disappointed in the jaggies, but the text was all crisp and clear. I read on the net that evidently the demo code (Call of Duty 2 specifically) does not have anti-aliasing enabled so there is still a chance that the retail version could look even better.
I've been reading all over the net that a lot of retailers are only getting 10-50 units at launch, and most of the specialty retailers (Gamestop, EB, etc.) are only getting around 20 at launch. It looks like if you want a launch unit your going to be waiting in line at Wal-mart, Target, or the like unless you pre-ordered real early.
