I think the fact that their controller will not have a motion sensor near you TV speaks volumes about it's presicion. I think Mario hit it on the head. It will be a worthless joke that only a few of the launch games will take advantage of, and then it will never really be used again. In fact, I wouldn't be suprised if 8months to a year later Sony is realeasing a cheaper version of the controller without that ability.
But what I want to know is more important. Even though WE all know its gonna be crap, will everyone else? Or will Sony's marketing machine have everyone believing that their controller is "just like Nintendo's"? Remember, this was the company that had gamers pointing to FMV's and saying Playstation's graphics are AWESOME! Nintendo64 cant look like that! Then, enough people, interested in the concept, but not ready to buy ANOTHER video game system after the hefty chunk of change they dropped for their PS3, will try the Sony offering. It will suck, and they will think; "Man Nintendo IS stupid! I sure am glad I was able to try this crappy flash-in-the-pan concept on a machine that will offer more than just THAT." If you think about it, bad word of mouth on motion sensing in general could get in circulation if Sony does this right. I wonder... would it be financially worthwhile to them to do that on purpose? Try and sabotage Nintendo's bid to show a new gaming concept? Given how things are looking for them in Japan.....
Well, here is the thing. Nintendo can actually make this work to their advantage, but there is one critical thing they must do. Launch BEFORE PS3. If they can get the Wii out in early enough, word of mouth about the system will have already spread. Then, when the PS3 comes out and people play a subpar version, they will be even ANGRIER about dropping 600 bones on that system. On the other hand, if PS3 gets out first, or very, very close to Wii, it could be yet another uphill battle for Nintendo, one they probably didnt think they would face. People thinking their controller "doesnt work" without ever trying their controller. Of course, people will become familiar with the truth after a while, but by then it will already be too late. Stupid Sony....
