Nintendo has the tech available NOW, the tech Sony and Microsoft has is not even in the market yet, and won't be available in the next year or so. There just can't be a comparison between the two.
Of course the tech Sony and Microsoft has could be better, because it was made after they have seen what Nintendo could do.
In Sony's case, from the demonstrations I have seen, I do not see how the Sonymote is any more accurate than Wii Motion Plus. There just is no threat.
Infact, if you watched the on stage demonstration of Microsoft's Project Natal of a guy trying to show us the bottom of an avatar's foot, BAM, there it is. It's not as accurate as people think. Until it is perfected to their vision video, I don't see how it could become a threat.
It would almost be like saying, "Hey guy, flying cars are more awesome than our current cars." Of course it would be more awesome, but they don't exist yet!
