Onkyo 552 receiver

http://www.onkyousa.com/model.cfm?m=TX-LR552&class=Receiver&p=i

I thought I had finally decided on the 502, but then somewhere this one popped up. Has it been recently released or have I just totally missed it?

How does the 502 compare with the TX-LR552?

From what I can tell, the 552 doesn't have WRAT, loses an input, and only puts out 65w (at 6 ohms nonetheless), but adds component video upconversion in a smaller package with some extra bells and whistles (onscreen menus, etc.).

As an A/V receiver, looks to be more V than A. But how does it sound and stack up to 502?

Also, I cannot tell from Onkyo's website specs if the 552 has A/B Speaker switching.

Any thoughts and opinions would be appreciated!
