IMO the evolution of video processing technology, as evidenced by the stream of ever more advanced chips, is allowing A/V receivers to finally deserve the "V" designation in "A/V".
This is particularly true in flagship receivers. However, as I see it, we consumers are faced with a dilemma. Because we are only in the middle of this video evolution, a purchase binds or fixes our video capabilities that may become outdated more quickly than our audio capabilities.
I wish that in order to address this receiver makers would design their video processing as an upgradable daughter card e.g. video card. Now that the HDMI interface is solidifying, I think this is possible, at least for chips from the same manufacturer.
Take the new RX-Z11. It uses the ABT 1018 chip. ABT is a fine company in this field and this chip offers excellent scaling. However, ABT already has the successor 2018 that integrates far more functions offering excellent de-interlacing and noise reduction as well. I would be very much more inclined to invest the vast sums necessary to purchase an RX-Z11 if I knew that I could upgrade video from ABT as time went by.
Let's face it, A/V receivers are becoming primarily special purpose A/V digital computers combined with some critical analog audio circuitry and amplification. The digital computer portion needs to be upgradable not only via firmware but in some areas by hardware as well.
What say you?
