The "revolutionary" new tech has to do with Room Correction (that actually works, unlike Audyssey that gives different settings when you run it multiple times...).

BTW, proper Room correction also requires massive computing power, so going with TWO chips is surely beneficial...

At that price ($1,400), I would expect it to have a good video processing solution - using probably either HQV Reon or ABT 2010.

And yes, I fully expect to see the CS 49700 in the 970 replacement (whenever it comes out).
