The theory some people have is that Qualcomm's acquisition of Nuvia last year was their attempt to get their hands on some desktop-class CPU cores (Nuvia was originally aiming for the server market), and Microsoft has largely partnered with Qualcomm on all their previous offerings. So that might be their saving grace if they can actually materialize something in the next year.
But I agree. Apple is pulling ahead a decent amount here and likely will stay in that leading position for a while, like they did in the phone space, and that makes all the competitors that much less appealing.
