I guess a key question is just how much content will be available in MQA format. If it's on par with SACD, which has still yet to reach 10k titles, then it's probably going nowhere.
On the other hand, I did read that Apple has ALL of it's 30 million tracks in 24/96 format. Doesn't that mean that in theory you could simply run a seriously huge mass conversion of those to cut them into MQA? Sure, would require a lot of CPU and processing time, but my guess is probably not much in terms of actual manual input.
