Yep I ll be surprised if we see Hololense under 700$.
Kinect + PC with strong GPU + Glasses + software.
I just dont see it being cheap in anyway.
Its funktions at launch are going to be extremly limited as well.
Meanwhile I can see VR set morpheus work just with a PS4.
Plug in and buy a game, and play VR games at probably under 350$ for one of those.
