The huge focus on motion sensor technology really wrecks the concept of the traditional video game for me...it's been tried before as various peripherals on several systems (ie NES Light Gun, SNES Super Scope, PS2 Eye Toy) and has always been met with limited success. It's not a matter of laziness that makes the controller, and now the Revolution itself, so undesirable, it's just that there is a limit to how much a controller should be able to do and what should define a controller. Games and one's prowess at games revolve around dexterity, which is an equalizer among all types of gamers, but games that involve motion can induce fatigue quickly in some gamers that would otherwise be very skilled at their craft...I, for one, don't want to be up and swinging swords, punching, touching, etc.
I'm disappointed that nintendo managed to turn the Revolution into what is basically a console version of the DS. I couldn't care less about interactivity, in fact I've found it to be hampering to the game experience. I think of the Super Scope and several arcade games I've played that involve swords and guns, as well as test Eye Toys at gaming stores, and I've found that with all of them they don't have complete accuracy; I'm concerned that a device in a controller won't even be able to stand up to what's already out; be angry at me all I want but I have very little faith in Nintendo's ability to deliver something worthwhile at this point. The fact that they haven't even revealed one game for the system makes me wonder if they rushed to make their "innovation", then sat around, puzzled, asking themselves how they could possibly apply this to anything now. I just have no idea whatsoever how this is going to be anything but awkward.
