Aside from 7 channels of amplification and 3 component inputs, it has some other interesting features such as "Dual Amp Technology" and "VGDA" (Variable Gain Digital Amplifier).

I believe the SA-XR55 was just added to the Panasonic site very recently... seems like a week ago when I was there it wasn't listed yet.

I'll be getting one in a few months

I see you can now pre-order it at J&R for $250, not bad.
