What?
"Wii killing" what?
Some people decidedly never learn, and will never understand. It's amazing really, cognitive dissonance at its best.
I don't even need to talk about the controller. People are so focused on the controller, but I repeat, how can you "kill" anything if you don't understand it? Especially when you will see it rise immediately back and get at you?
It seems there are people that actually believe that if MS makes a new motion sensing controller for free, they will get the Wii wanters with an XB360 Arcade?
Who in his right mind believe that people will fall for:
- a console with a complicated name when they asked for the Wii
- a big box with a big power brick when they asked for a classy Wii
- a noisy box when they asked for a quiet Wii
- a game that will most likely be crappy and without any Mii, when they asked for a Wii which comes with Wii Sports
Who?

That doesn't make any sense to me. People that are looking for the Wii killer are missing the point as much as people that are looking for the iPod killer. There are tons of things to fix before the competition can even think of doing damage to them.
Sony's attempt is downright irrelevant as it goes completely unnoticed... fortunately for them, unless they push Wii domination even more.
Better hope that MS attempt goes unnoticed too, unless they see Wii domination increasing even faster, without understanding why.

It's actually funny, because you can see another huge cognitive dissonance in all this (denial if you prefer). There are two actually:
- people say Wii will die if it doesn't do HD, but Nintendo isn't doing anything to go HD and is crushing the competition. These people just refuse to acknowledge all the other things that make the Wii a success (except price, as it seems even cognitive dissonance can't bypass that)
- people still think of the Wiimote as a fad, but look thoroughly for any news about the competition doing a wiimote like to then "kill" the Wii

This is so funny :))

"- people say Wii will die if it doesn't do HD, but Nintendo isn't doing anything to go HD and is crushing the competition."
How do you know Nintendo isn't doing anything to go to HD? HD is clearly a factor when it comes to modern games. If a gamers want games in HD he has three sources; PC/360/PS3 while the best Wii can do is 480p. So who knows if Xbox has a Wii like controller plus HD may just pay off in the long run. If Mircosoft is successful then they have my vote since I prefer games in HD.

The only reason the xbox/xbox360 is go good is because they steel idead from other systems!!! All the good ideas started from nintendo and then sony and microsoft took them!

The one Microsoft might make or the one in the picture? The one in the picture is an early Wiimote prototype.

I rather expected this might happen eventually...

The only time a late-game addition to a console's controller line-up ever does well is if it offers something particularly noteworthy over what else is available across not just the system's own platform, but the competing platforms as well. This is why the DualShock took off (two is better than one, or so the theory goes), and even then, you saw very few DualShock-exclusive titles on PS1. Just support-if-you-have-it titles, for the most part, until the PS2 came out with already-integrated dual analog sticks.

The 360, if it does get a Wiimote-esque, will likely not have a lot of support for it. Probably ports from the Wii will add support for it (almost definitely, in fact), but it won't ever be a mandatory peripheral for more than a handful of titles, and definitely will not be a must-own component.

Its never too late! Turn that frown upside down!! :(    --->   :)

I wasn't attacking the PS3, I even mentioned the PS2's Eye Toy rather than the PS Eye to avoid bashing the PS3 ... The Eye Toy was remarkably popular for an add on device having sold somewhere between 5 and 10 Million units; in a market which normally rejects any add on this was a major feat.

The problem with all add-ons is perfectly demonstrated by the Eye-Toy though ... The device never received any third party support because third parties knew that the device would never be popular enough to justify the development of any games; this limited the device to being a niche product that would never appeal to the masses.

Now a smart company might attempt to combine the sensor bar with a high resoultion, high framerate, digital camera for their next console so that they can use their systems standard hardware to produce Eye Toy like games, perform head tracking, video conferencing, and provide screen pointing capabilities.

it won't be a wii controller killer as stated by the demographic differences but just another thing thats being stolen from nintendo

I have to wonder, did anyone bother to read what it said there, and not just look at the shiny picture? within the first paragraph is plainly states that the picture shown has been fake(and I'm pretty sure thats the same picture used years ago when people started talking about the wii(in fact it also points out it was the picture used for ninteo back in 2001). I know it's also talking about microsoft researching 'new' technologies for input... but.. who isn't? come on now, why would they NOT be looking at nexgen stuff already? Go google wii prototype picture, or something similar and you will find that exact picture, when I first saw it years ago I was hoping they would make the break away type controller, and wish they still would, so you could use it as a traditional style or new 'wiimote' style as well(but of course you would need a power source for both sections).
