I will be curious to see the differences in the 978 vs 998 (aside from Audyssey vs Trinnov).

I'm sure it is a bit early to see the specs in each, but prior to the 978 release:
I'm very interested in timing difference between releases and differences in feature/hardware specs.. Hopefully we will know more on the 998 prior to the 978 release to help us know how "inferior" the 978 is. Not sure that it will be too inferior.

Trinnov has me curious, but so does Audyssey XT32 (assuming the 978 has this)
