Can't you feel it? This years E3 is going to be one to remember for sometime (at least a year anyway), with so many titles being mentioned needing clarification, inFAMOUS 2, Agent, Gears of War 3, COD: Black Ops, there is plenty to be tense about and there will undoubtedly be more reveals than you can fit in your pants. But I think this year is most notable for the motion controllers role.
Ultimately I think that a regular, normal, normal, regular controller will always best anything that involves motion, mainly because there is something to be said for pwning enemies without breaking a sweat, and for that reason I will be interested to see the public response to these controllers; but I find it hard to be optimistic. The wii's controller is two poorly designed, with a nunchuck, motion plus, vitality senser and a bunch of other useless trinkets the thing guzzles batteries like a battery guzzling gaming pad (hmmm?).
As for the Natal my problem with that is its complex nature. The thing takes a half dozen environmental readings to create a game input and with the frail nature of the XBOX 360 I wonder how well it will perform outside of a game demo. Also I don't see the main audience for the 360 being at all interested, they are a hardcore gaming bunch after all with FPS dominating the most sold on the platform. Then comes the Move.
Perhaps the most hopeless of the bunch, but then that wouldn't be saying much as they are all pretty terrible, this thing utilizes a coloured diode ontop of the controller which can be connected to a second coloured diode or a sub controller... The design is just ugly and a somewhat blatant copy of the Wii, which may explain the reason for its prefail, but my biggest gripe is that it seems to have no decent games and it just smells like a Sony propaganda novelty in the same field as the eyetoy; which was barely more than a web camera. At least Sony has its target right though, going after the wii's audience is definitely the right move and they are certainly the most experienced with motion controls, even thought the eyetoy was pretty shocking, but only time will tell to see how big a disaster this whole thing turns out to be.
Just to reiterate, E3 willl be made by the games not the novelty controllers. Uncharted 3 FTW!
