The main point here is that this news might be fresh now, since E3 is going on, but they quickly forget what they reported a day or 2 ago for the current news. Since NATAL wont be available for a year or more, the major stations will have long forgotten about it, as will any potential interest. The target audience for NATAL is geared towards casuals and super-tech people. The super-techs will remember, but they likely already are 360 or PS3 owners. The casuals have a 3 day consumer attention span. If they don't get reminded of it, its out of their heads within 3 days.Thus, all the E3 news will be dead to them by the weekend.
I don't deny that Natal looks cool, I just dont see it being the "Wii-killer" that a certain fanboy screams it out to be. It'll have its use for the 360 fanbase, but the casuals wont make the transition.
