I'm not sure if Microsoft actually wanted to try to make it a success. They made a lot of decisions that didn't help it succeed, with one of those decisions leading to every headset being a brick (officially, although Oasis fixes them) now. I could go on and on about it, because I love my Odyssey+ and it's frustrating to see how they screwed the ecosystem up so badly.
But I still remember the uproar in various communities about Samsung’s decision not to release what was, at the time, the only premium-tier WMR headset, with higher resolution and refresh rate, a wider FOV, mechanical IPD adjustment, and a few other features.
Only the HP Reverb WMR headset, released about two years later, offered comparable premium features and launched in more regions. But in my opinion, by then it was already too late.
The thing is, even at a slightly higher price point, the Samsung Odyssey would have been a great entry into PC VR for many people, since it was still one of the most affordable headsets compared to its competitors at the time, like the HTC Vive or the Oculus Rift.
That alone could have helped WMR gain more traction. But many reviewers weren’t too impressed by the other WMR headsets from different manufacturers. Some even compared them to the Samsung Odyssey and suggested waiting for Samsung to release theirs worldwide, since it was clearly the better one (at that time, in 2017).
I’m still very salty about Samsung never officially releasing their Samsung Odyssey VR headset in Europe. It was the best VR headset among the Windows Mixed Reality headsets at the time of their release.
Of course, the HP Reverb was better, but it came out much later, too late for WMR to really take off.
I still believe that if Microsoft had forced Samsung to release the Odyssey VR headset worldwide, WMR could have been a success.
And I’m pretty sure Samsung won’t release this one (the Galaxy VR) worldwide either, which will be the reason it fails and Google will probably take that as an excuse to shut down the project as well.
