Well let's see here:
Move: Um, we're assuming Sony is actually going to be able to come out with any good games that would make me want to use such a thing which we know they won't so why bother discussing it. Sony is basically just jumping into the Nintendo playpen so why don't we let them sock it out over which is the most worthless platform for serious gamers.
Natal: Obviously I'm not going to use it to play JRPGs or Visual Novels so why the heck would I care?
Wii: Again even in the off chance that I ever touched a Wii the only games I would play on it would be stuff like Fire Emblem and Phantom Brave which require no use of motion sensors so who gives a flying Pooh?
All in all motion sensing games are just a gimmick and have nothing to do with any of my favorite genres. The only games that are in any way influenced that I can think of are shooters where you get to point the pointer at the screen instead of trying to manuever with your controller. But as soon as we hit that point we might as well be using zappers which are cooler anyway. Plus everyone knows it's best to use a mouse for FPS games in the first place so the point is moot.
In other words: These three pieces of technology are less than worthless and the companies should throw their money elsewhere thank you.
Algus: It is the Will of Heaven!
Miluda: Heaven? God would never say such things! In His eyes all are equal! He'd never let this happen! Never!
Algus: Animals have no God!!
