Interesting, we launched Truepoker in 2001 with a 3D, first person user view, looked a lot like that version above. Players each had a unique view of other players at the table, each of whose actions was observed, including picking up hole cards to look at them, etc.

By 2003, we looked at building Truepoker into a virtual reality "first-person casino/poker experience, which was definitely possible and would have been an entertainment product*, but its appeal to poker players was uncertain.
The online market at that time demanded speed of play, X+ hands per hour, multi-tables. What the market wanted was a flat, 2D presentation, more adaptable to multi-tabling, than an immersive environment, where you walked into a poker room, looked around, sat at your table and played about 20 hands per hour, then got up, walked to a bar, talked to other patrons and had a drink, etc.
Times have changed over 15 years, and clearly there may be an "entertainment" market for this virtual poker, but I do not forsee it gaining traction among folks who simply want to play poker, versus playing an immersive, VR game experience. (Of course, if you have 70% of the market already, offering new products for various marginal market segments to try them out makes sense.)
