why does people think the Vitality sencer will be a boring moment? we hardly know anything about the device and how it actually works other then heart rate

As history tells us, Nintendo and Sony don't really "get" what we want from E3(IE Pacing of the show, big ending megaton, announcement of surprises instead of already known bullshit, ect) like Microsoft does(though last year, Sony did step it up a notch but why didn't they save KZ3 for the show?). The motion controls will increase the chances of live demo embarrassments, so that is the only reason I can see Microsoft having a moment like that.

Nintendo, however, almost certainly will have at least one cheesy fail moment guaranteed.

MS might have some accuracy issues with Natal, and that gives them a significant chance at failure as well.

Now only is it an aweful and unnecessary idea, it is also depressing and morbid. I don't want to think about my low blood pressure or above average heart rate when I'm playing damn mario. I do not want to be hooked up to an EKG machine, or any other hospital equipment during an escapist venture like videogames, and it pisses me right off.

Nintendo will have the least favorable show even though they might have some cool things compared to past years.

I reckon there will be some embarassing moments from all three but that doesn't mean it'll be an embarassing E3 Conference at all.

Like imagine the Wii Vitality sensor stopped working halfway through a presentation. Or Someone demonstrating some Move game that requires lots of swinging that the Move Controller accidently slips out of his hand and into the audience. Or Natal clearly shows significant lag and the presenter says it's Lag Free or showing off some ridiculously funny Natal stuff like the woman last year demoing the hit the red balls demo.

There could be those moments but they ain't gonna ruin anything. There'll only be youtube clips of the embarassing moments itself.

microsoft will be hilarious, but assure u they won't show much, all that scifi thigns they promised will left out and simplitic motion control wil be shown.
