The issue with receivers changing every year really isn't the fault of the receiver manufacturers. Rather, we've had about ten years, maybe more, of ever changing signal specs. 1080p then 4k, then HDR, then Dolby Vision, then .... Not to mention HDMI 1, HDMI 2, HDCP 1, HDCP2, HDCP 2.2...
I suspect the manufacturers have responded to this by building finite numbers of units (even if that "finite" number runs to six or seven digits globally). When those sell out, time for a new model and time to catch up with whatever new codecs are needed.
Some receivers have been moderately future proofed with updatable firmware, but there's only so far that can go.
Whilst that is somewhat true, it isn’t the main reason for annual changes to AV receiver ranges. Firstly, once reviewed, a product is generally never reviewed again unless it is part of a big super test, which seem to be becoming a scarce occurrence nowadays. Also, there have been years when the only change has been adding something as superfluous as Bluetooth (not actually anything beneficial for movie viewing), or just dropping a feature or two to the next model down. There seems to be any excuse to change nowadays as it means getting re-reviewed and back in the public eye.
Changing every year just kills used prices, as people know they’ll get an end of line bargain every year without fail, and surely costs manufacturers money in updating so frequently - manufacturers don’t lose out as they get their full margin, but retailers suffer virtually as soon as a model is released as there’s the initial rush from retailers to get as many sales as possible from the demand of a new product. Saying that, retailers generally have themselves to blame for much of the price wars and profit losses with AV receivers.
Many additions always seem to be half way houses. When 4K was added, many receivers got one 4K compatible input. This wasn’t HDR compatible, and I don’t think some of the first were even HDCP compatible either, which got added with future new model releases. If you’re going to add a feature, do it properly, just wait a year and make all the inputs 4K and HDCP compatible - as this would completely remove any confusion for future used buyers and sellers.
Personally, I think they should run for two years, that way it would bring some stability back to the AV receiver market, give buyers better trade-in/resale prices, and give retailers better margins. And when it does come to update time, at least there’d be a number of additions or features for the new model, and more of an incentive for people to change.
