Depends on how much effort Microsoft is going to put into updating the WMR platform, which hasn't seen much in the way of improvement recently. Though Microsoft did announce the other day that they're uprading the chromatic abberation correction, so it looks like they haven't totally abandoned it.
On the Freality podcast they said the main issue with the controller tracking is that it's not as quick to re-aquire as Oculus's Insight tracking. With the Oculus system you may lose tracking but it recovers very quickly - in fact you may not even notice you've lost tracking. When WMR loses controller tracking it's very obvious, and doesn't instantly recover.
It is frustrating though that there's no definitive headset yet. The Index is close, but is expensive, has lens glare and the resolution is now lacking compared to Quest 2 and G2. The Quest 2 is close, but has forced facebook, compressed PC graphics and not very good IPD adjust. The G2 is close, but has comparatively worse controllers, etc.
