I believe so, and presumably this would be achieved through MHR and/or SL (and legacy?) comms.

Yes, this is the logical conclusion - it is highly unlikely that M would allow other manufacturers to use the MHR system

Agreed, but the AC200 should not need to be replaced - it will simply stream bit perfectly to the MQA/MHR compatible endpoint (such as the replacement for the MS200).

One other possibility, and this is pure speculation, is that the current MS200 and MS600 could be firmware upgraded to give decoded MQA on the analogue outputs only - this would at least allow some full fat MQA functionality on these machines with, for example, headphones or analogue systems (and would be a good PR move too). I understand that going the whole hog and making these machines both MQA and MHR compatible via firmware upgrade is not possible because of chip limitations (unconfirmed but believed to be true).
