Of course it was shot the same way they did Avatar.
They do this for a long time. Every amusement park uses the same technology - including polarized glasses - as Cameron, since over 30 years.
There is nothing new here, only the hype. If you tell people long enough it´s new and groundbreaking they start to believe it. And even better (for the propaganda) they start to believe they actually see it.

The basic tech is the same, but it's been refined, and that makes a difference. Cameron's camera system has lenses that move as the depth of field changes to eliminate convergence problems. Also, digital projection improves the 3D experience as the image is more stable than polarized film projection. I've seen all kinds of 3D over the years, and RealD is an improvement over past systems. The only thing as good in the past was 3d IMAX.
