I really do want 60 Hz, yes. And you don't really need positional tracking for watching movies. Also, I'm actually a bit skeptical about the 200 degrees FOV. Maybe it's me, but my Rift looks worse the further from the center I look, and my Gear VR even more so. I think I'd rather have perfect looking 90 degrees than 200 degrees with lots of blur and artifacts, if I had those two options. (But I'm not sure.)
All VR headsets seem to have their problems, and some people experience problems that other don't, with certain headsets. And given the rather extreme specs of the Pimax 8K, I'm afraid it might have more problems than other headsets. I hope they prove me wrong, though!
Maybe I'll get the 4K and the 8K.
