I am very interested in this and will likely buy it once the new NV graphics cards ship later this year.
I have a 43" 4K 60Hz monitor, Korean made and it is absolutely beastly. I have a 1080Ti on water to drive it and the immersion is fabulous. Battlefront II is like being in a movie with all eye candy turned up to max and still get 100fps.
Since my 43" monitor is made as a monitor, the bezels are thin and the stands are out of the way, so it is very comfortable as a desktop monitor and doesn't resemble a TV at all, because it's not. It has a small form factor. Since it's a Korean monitor, the panel is LG and I paid a little more for the A+ rating, meaning no dead pixels. I paid $500 for it 2 years ago and its 10 bit color and Chroma 444. Battlefield 1 is absolutely amazing on it.
Wasabi, Catleap, etc have been around for a long time with a strong track record, including the old days of finding panels that would over clock your monitor to 120Hz on 1440p. Don't be afraid to purchase a Wasabi from an Ebay seller, it's not a junk company and the panels are likely all LG anyway.
The fact that Wasabi is releasing this monitor gives me hope that finally we will see a push into large 4K monitors at 120Hz since these vendors were the ones who initially pushed 120Hz on 1440p while the main stream manufacturers were a sleep at the wheel, and still are in many ways.
Good on Wasabi, this means happy days ahead for PC monitors.
