If you tried a prototype, the resolution was much much lower than the final hardware. The final resolution is 2160x1200, and while still not as good as your pg278q, it's much better than it was.
I'm not sure what version it was. This was at NASA JPL earlier this month and someone was showing me their work. However my understanding is that the final version is 1080x1200 per eye. Your 2160x1200 is adding the two together. My monitor is 2560x1440 per eye, at 72hz each (144hz total). What I don't get is why the existing fantastic 3D technology is barely used at all.
