There is no mention, as yet, of this being a 2D/3D combo and the price is more in line with a 2D only edition.
This is from Universal, the same studio that gave us "Jurassic World". It's worth remembering that a number of the European Steelbook releases for that title, including France, Germany, Italy and Spain, only include the 2D disc.
