The more stuff you add to an AVR, the more things there are to go wrong or become outdated. Not in their defense, but they are in the business of making money, not making consumers happy. They have to include "bells and whistles" to get the less than knowledgeable masses to buy. The average consumer buys a receiver, or most home electronics, based on "which has the most features" not real world performance, simply because it is all they understand.
I already did say no. I don't have every brand new feature out there, but I have also only changed my non-big name Pre/pro twice in about 8 years and I am still happy.
