For architecture I think it's getting more rare where a client wants an actual full model unless it is for public display. The models are stuck at a single scale, and what ever detail you have you are stuck with. No room for easy revisions and refinements, varying detail levels, lighting, etc. Kind of all the same reasons we don't draw by hand anymore. A good 3D model they can navigate with something like kubity is usually enough for most, or custom fly throughs with chosen focal points. For custom shapes, profiles and molds there could be a use for it in part building for detail work and such.
The augmented reality shown is nice for the sales pitch like what they showed and maybe creative big league stuff that is just outside my scope. VR based on a 3D model would be more appropriate in the near future looking at the tech I see coming down the pipe.
Lowes jump onto the AR bandwagon with Microsoft's Hololens is a little too early I think, but it might wow some now while the tech catches up. It will be the future, but think we are still 5-10 years off to semi-mainstream. CD's will still rule the day for some time after.
Outside architecture, 3D printing is going to change the world we all use everyday, and soon, if it hasn't already.
