*Edit: oops it's only the 65nm cpu that has been confirmed (to my knowledge), I should have linked to the original thread on xbox.com that this story refers to.

"News has come to light that some of the Halo 3 limited edition Xbox 360 consoles incorporate the 65nm CPU and GPU, which in essence make the console more reliable and less power hungry than the normal 90nm boxes which are to be found in every other Xbox 360 console released to date. We were all unsure when the 65nm consoles would hit, but it took us all by surprise that they have indeed debuted in the Halo 3 machines and not the Elite. However, finding out if you have the 65nm console isn't easy, as you need to take your console apart."
