It's an interesting concept, but I am not sure how it would work with Photoshop? How would you hope to use it? Would it be for teaching Photoshop? The UI is essentially flat and two dimensional, and even with 3D objects inside Photoshop, I wondering how this might be useful. Have a look round for Photoshop Virtual Reality.
It would allow creatives to develop advertising campaigns dynamically using Photoshop, Illustrator, and other Adobe apps as 3D. They could use it as a mechanism to share and collaborate. Advertising agencies would love to have an aspect like this because it would allow then to innovate faster. If you've seen the minority report with Tom Cruise, that's something I have in mind. The screen would still be 2D but the screen would be projected in front of you with the tool options to quickly assemble it yourself.
If Microsoft can use Hololens to use excel and powerpoint, Adobe could have the same tool but better.
