Nope. Not going near them. Having tracking 'mostly good enough' is a VERY bad idea, particularly when you'll be able to get a Rift and Touch for $400 pretty soon. It'll be $400 during their Christmas Sale and if it doesn't become a permanent price after that sale it'll become permanent in March or April next year.
The Tested guys tested these things in controlled conditions, a lot of the PSVR tracking was thought to be 'good enough' in similar controlled condition demos but the tracking proved to be a steaming pile of old shite once people got the thing into their homes.
The Pimax 4K headset (no, I'm not calling it 8K!) might be worth getting because they seem to be making great strides as far as the displays goes so it should be pretty decent by the time it launches but I'm not going anywhere near these Windows VR headsets myself and won't be recommending that anyone else does either.
The bloomin things won't even have Steam support at launch ffs
