To hear Microsoft and Sony tell it, you'd think that there's no question that Kinect and Playstation Move will each become as integral to their respective consoles as a regular controller is. But not every game publisher is hopping on board just yet, and Activision is now publicly voicing some skepticism about the motion controllers. Speaking to Gamasutra last week, Activision COO Thomas Tippl said that he is "absolutely" concerned about what he considers high price points for the devices, and as a result he says that Activision will "have to see how much of an install base they're going to develop." Tippl further goes on to say that Activision has "few franchises where we think this could be an interesting value to improve the experience for the player," and that he doesn't see it as "something that will be in every game, because I don't think it's one size fits all. It's not going to enhance the experience for every game." He does ultimately leave it in the hands of consumers, however, so if Kinect sells, we could well finally get a proper Air Guitar Hero game.
