Those things look different, and different is good (sometimes). I am probably going to get the nintendo revolution when it comes out, and when I do the first thing I am going to try is duel-weilding those things :D
That controller looks like someone was to lazy to put any thought into it.
I read ohter articles on the controller and have talked to a friend of mine that works at a game store and this controller will be SWEET!!! Just think about it. Nintendo already has awesome liscenses to use with this and now the prospects of an awesome, innovative FPS for Nintendo are now evident. Also, think of a game like LoZ where you can slash, parry, and stab if you want to.
