If this is true, then I might bite - in the link you can see pics of the exhaust of the 480 vs 485.

From KitGuru:
So what is the GeForce GTX 485?
Simply put, it’s what Fermi should have been at launch.
A little quicker. A little cooler. A little easier to make.
With the earlier price move announced exclusively by KitGuru, we’re now expecting the GTX485 to come in around $20 higher into distribution than the launch price of the GTX480. It will also overclock easier, because more of the pesky electrons will be going where they are supposed to go. Nice.
KitGuru says: Interesting move by nVidia. VERY unusual for the company with the single fastest chip to beat their own product within a few weeks of launching. We guess that Northern Islands (the revamped Radeon 5000 chip) must be very close to launching and nVidia wants to push every soldier it has into battle now. Good news for nVidia fanbois who have been holding off on GTX480 because they were not sure about all that heat and noise.
