We haven't even seen a Vitality Sensor game yet, so it's unfair to judge it now. The hardware looks pretty uninteresting, but so did the Balance Board without the software to go with it.
Move is going to bomb. It is basically a "Wii HD". Most people will look at this and laugh.
Natal has some potential. It is a unique idea at least (sort of). The e3 trailer made it look awesome last year, but then most of that was probably fake. If those ideas actually get made into playable games at this year's e3, I think Natal is actually going to be quite successful.
Still, I don't think any of these will ever be as successful as the Wii Fit and Wii Fit Plus. 34 million in sales is a lot!
