Thats great news. My NEC20WMGX2 might have a worthy replacement!
Yeah I think it's safe to say they'll be giving even high end brands a run for their money with this. I wouldn't doubt if NEC will eventually put out an e-IPS display.
Here's another review, from France, that shows some more tech info, including input lag. Apparently that 2ms display it was compared to in the other review was not so quick after all.
Still though, 20ms (roughly 1.2 frames) is not exactly horrible, just not the best.
