Kind of wish they hadn't released a teaser for something so heavily anticipated and with so few public updates. Really sets the bar higher than it needs to be.
If they improve the FOV this might be amazing - I tried the first iteration and it worked quite well. Very excited :-)
Apart from the FOV and the crummy controls (the gestures were very unreliable and it really needed Vive-esque hand controllers) the first Hololens was basically perfect: object tracking was spot on with no lag or jitter and the holograms looked great. So this could be a real hit if V2 addresses those two pain points.
