It’s completely wireless and requires no additional hardware (neither extra sensors nor a $1500 PC). That’s leaps and bounds beyond the first-gen Vive.
I'm not saying that there hasn't been substantial innovation. Indeed, these things are major upgrades. But it's still "evolution", not "revolution" - these upgrades don't enable any fundamentally new experiences, it's still 2016 VR style experiences in a more sleek package. The cynic in me thinks that this style of VR is fundamentally flawed, and more major innovations are required in comfort, display, locomotion, and haptics to get VR to the point where we are ACTUALLY all spending most of our time in the Metaverse.
