Ok the Falcon part is just pure speculation. However, sources are claiming on xbox.com forums that the recent bundle for the Xbo 360 Pro System now touts the 65nm chipset.
“I got a Pro system bundle with MUA and Forza2. Has HDMI. Lot 736 manufacture date of 9/6/07. Team FDOU, S/N starts with 613. black DC brushless fans, BenQ drive”
“Looking inside there is no copper pipe, just a gap in between the black capacitors. My wife and I took awhile trying to take decent pics of it. We can see inside clearly but its hard to translate it with a camera. Sorry if they are too blurry or hard to make out”
Comparing these images with the images released for the Special Edition Halo Xbox 360 it is confirmed that it is certainly a 65nm console. I’m glad to see that at least some of the new bundle packs have 65nm.
Now other reports are saying that some people have the same Lot 736 w/ HDMI but it is not the falcon motherboard. So here is to hoping that yours will ship with the new Falcon boards.
