When the question is DolbyVision and HLG, it is probably not a good idea to bet on last year's hardware unless it is already proven compatible (especially if you're a DIRECTV subscriber where HLG seems to be the order of the day for UHD programming). HDMI capability has been the keystone to AVR longevity for a while now and to get stuck with something that can't do all the latest HDR and WCG stuff would be a terrible shame.
I understand what you are saying, but I've been at this since the 70s, and there are other factors in play.
Rule #1: You will pay a premium for the latest and greatest.
Rule #2: in a year, your latest and greatest will be obsolete and there will be a new latest and greatest. It is a fundamental rule of merchandising.
Rule #3: with rare exceptions (HD-DVD anyone). last year's equipment will continue to function at the level it was designed for. You may be missing some groovy mode or feature, but there will be a lesser mode that still functions.
(even HD-DVD still plugs into todays receiver and plays movies. Although I can't get new ones, I still enjoy all those $1 titles bought during the closeout)
I don't deny that there are folks who are willing to take the hit and update every year, but the people asking in these threads are trading in 10 year old receivers. This is similar to my philosophy to buy good stuff and then ignore the latest and greatest until the equipment limitations are too great to ignore. About every 10 years.
FWIW, Harshness, I never actually advocated buying last year's stuff. MY comment was along the lines that if price was a primary concern, you would be looking at the previous model for a given level of performance. This might be perfectly acceptable to many. Say you have $1000 to spend on a new receiver. Which is the better buy? The new one with features, or the year old model with higher power and more channels? Careful, there is no one right answer.
Its a matter of education, and I was advocating that in my post.
