This is one I've been waiting on as well (as I also can't justify the 80$ CAD). I sadly have terrible experience with Gamepass though so I'll unfortunately be just waiting for a good sale. Last time I tried Gamepass it hit a known and un-fixed bug where it doesn't pop up the admin install request, so I can't actually use most of the games on the service.

Anyhow, super looking forward to this third installment. The first two were great, and I honestly should go back to TW:WH2 for more, as I never did play all of those factions.
