Gates laid out his vision in four words: touch, ink, speech, vision. Was this a subtle jab at Nintendo? We don't think so, though Gates' quick response to Mossberg's statement gives the impression that he was prepared for the comment. Simply, Gates feels that long down the line, it will be better (though he admits there are privacy concerns) to use video recognition for the same functions, and his words apply to all technology and not just games. (It should be noted, however, that Gates' opinion of the Wii and its controller have undulated over time.)

Speech as an input is something we're starting to see more often (e.g. Tom Clancy's EndWar), and touch has been prevalent with Microsoft Surface, university research and the "money-printing" Nintendo DS (though that might fall under his "ink" category, given the use of a stylus). Video recognition is also something that has worked with mixed results, though games like the upcoming Eye of Judgment show a clever use of the technology.

But, returning to Gates example, is swinging an actual tennis racket for a virtual environment the best choice? Later in the interview, from Steve Jobs, talking about the post-PC market: "They don't want to drive with a joystick, they like the steering wheel. And so, you have to ... as Bill was saying, in some cases you have to augment what exists there and in some cases you can replace things." Perhaps in this case, the use of a small, plastic wand as a replacement for a racket is more ideal in an indoor environment. It certainly lowers the risk of breaking anything -- or maybe not.
