It's an interesting concept, although what they're showing here is mostly smoke and mirrors -- it's all a projector, a single unit. Somehow, you'd have to get the pieces to "talk" to each other (or talk to a central processor), to say nothing of getting the pieces to be self-powered, self-contained OLED displays that you can twist, turn, and position like they were showing with those pieces of white paper.
The good: fewer lost pieces, less arguments over rules, presumably less time to set up/clean up, more focus on playing the game and less on administration (when playing Monopoly the board game, did anyone ever take the "10%" for income tax? A computer can tally up your property values in an instant; in the board game, it was always the default "$200").
The bad: power, maintenance (how long will these things last), each piece is a lot more valuable (can't just draw a new Catan hexagon on paper or substitute a GI Joe for a Monopoly token if the hexagon or token is an electromechanical OLED screen or radio-enabled gadget), can't make up your own rules (maybe?).
The ugly: Going to be a lot more expensive, make me feel positively ancient ("You mean you have to use your hands? That's like a baby's toy!")
