There here to stay. Htc is already testing a set-top box with a monthly fee. No pc required. Think there still trialing it in China.
Oculus tracking is decent but still no where near as good a Steam's Lighthouse tech.
WMR & Vive can be easily used with a vr backpack since tracking is built into the headset. (Lighthouses are not wired to pc).
Yes Oculus has ASW; which has nice gains; but HTC while overpriced does have the Pro while Oculus drags their heels at present.
Coming out first always has it's drawbacks. Granted if Oculus hadn't aggravated Valve; Valve was going to share Their tracking tech prior to Fb buy in. Wands were loosely based on previous Tracked controllers ie WiiMote & Psmove etc..
Oculus took forever to release controllers; so they had to be evolved to what was out. This also demoed folks like of stick.
As for SDE sure Vive has noticeably more. But how noticeable if you match the rift's brightness?
If we weren't still stuck in the Proprietary Era, we could have the best of both worlds.
Yes HTC dropped the ball with the Pro but it's still selling. Sure this stupidity will allow Rift or really WMR headsets a large gain in Market share.
WMR truly poses the greatest threat HTC & Rift. If they get their tracking really effective & relesse something even better than the Odyssy... Well Portable easy setup - Nuff Said.
