Expectations for warranty repair timing

Never would wait 3 months for repairs this is totally unacceptable not a very good company.Would pass on there stuff big time.

"  If it were an issue of locating parts or something else specific that's delaying things, that's fine - I'd just like to know what's going on and what timeline I should expect."

That's important. A good company will always buy enough parts to service their products long after the model or specific parts are taken out of production.

The trouble with a thread like this is that the repair time is dependent on the amount of backlog a company has... Also, if they have changed their repair strategies.

For example:
Naim had a Naim, USA repair center at some point. They were very responsive. Then they went to an independent repair center. A recap of my Naim kit took 5 months, no calls, no updates, moving targets each time I called. 

VPI: A spindle bearing replacement took 4 months on my 13 year old TT. No calls, no updates, moving targets each time I called.

McIntosh: In the late 90's, my CD player needed repair. It took 3 months to fix. The unit came back with the same problem. Another 2 months to fix.

Linn Sondek: The power supply needed replacement. The dealer fixed it in 2 weeks. The dealer no longer is in business.

I now have backups on all my gear and no longer worry about repair times. To me it is a black hole, life is too short to fret about it. I do call periodically (emails are useless) and listen to the usual stories, but I take it all with a grain of salt.
