This is really cool to see, though it was already confirmed to be coming (eventually).
I'm actually in the market for a new TV right now since I'm still on a 1080P set from several years ago, but I won't jump into 120hz/VRR just yet since the tech doesn't seem to be quite there for the price. I'll just grab a decent quality 4k TV with nice HDR and call it a day, and upgrade in a few years again when VRR is more stable and there are more games to support it. The one I've been eying is the TCL 5 Series (5S535). It's only a little over $500 CDN for a 50" which is more than adequate for where I'm planning to put it, and it's not expensive enough to where I feel guilty in upgrading again in a few years.
