Both Denon and Onkyo (and their sister brands) - have sold most of the stuff they could make...
Both are working with 2021 models
There have been remours from both with regards to new models...
For Denon/Marantz - the rumours are around a possible xx800 family to be announced 3rd Qtr and maybe release 4th qtr
The biggest rumour, is that D&M will jump ship to Dirac - but this is pure hearsay
For Onkyo, there was some intention, late last year, to announce and then release their flagship models.... - so the 2021 range included the mid market Dirac models NR7100 & RZ50 - the early 2022 plans were originally to announce the RZ70 & RZ90 flagship models - and sister brand equivalents.
But it never happened - no one has any solid info - there were some rumours emanating from Dirac, that the new Flagship models were going to include new Room EQ software (Dirac Unison?) - but nothing more to substantiate it.
If there will be 2022 AVR's/Prepro's, they will most likely be announced in late 3rd Qtr, and some stock (limited) might become available towards the end of the year.
Having said all that... Onkyo/Integra/Pioneer 2021 models arrived in Australia in early 2022 - I purchased an Integra DRX 3.4 - what I wanted from it was a good pre-pro, with current formats, HDMI 2.1, and Dirac - power for surrounds and heights being onboard is a bonus - but my mains were always going to be run by my external power amps.
Improvement in performance over my 2013 & 2008 AVR's was dramatic - and primarily down to Dirac
