I currently have an HTC Vive, and there are two things that I'd like to see in whatever VR set I get next. The first is that I'd like to get higher resolution. VR is pretty nifty and immersive even right now; however, text can be rather awkward to read... especially with the Vive's sweet spot problem. (The sweet spot is that text is pretty much only readable at the center.) The second might be one the most important of the two, and that's a good wireless implementation. Unfortunately, graphic intensive games will still require processing outside of the headset, which means we need some way to get rid of the cables. Some companies went with backpack units, but at best, they last around 2 hours per battery. We've seen a wireless entry from TPCast, but it's not exactly the most elegant solution nor is it without issues (both hardware and software). There's another company that created wireless VR tech based upon their wireless docking station technology, but they're looking to license it rather than create their own.
All in all, the PIMAX 8K likely checks off the first box as I've heard plenty good about its screen. The only problem is that while they've talked about a wireless solution, we have no idea what it is, how well it works, or how much it will cost. I'd really like to wait until I hear about enough in both areas before I invest again.
