except sixaxis was not that supported, not needed AND not that much functionnal

NAH II lol

Indeed, it is very important to seduce the core gaming TOO.

Because, the casual, they dont consider at first buying a 360 and they dont have a 360 (so it costs more to jump in). They may not even know kinect right now. It may change with kinect release and party games and marketing but it will take some time.
So the very early adopter (week1) are Xbox360 core gamers that want to try kinect (overhyped on internet since E3 2009) or core gamers with children or casual already having a 360.
Indeed, it is like the early adopters of the Wii : big Ninty fans that wanted to play the next Mario/Zelda, not that much casuals people looking for Wiifit.

So it is very important to have those early adopters buying new stuff and showing these news stuff to their family, friends, neighbour etc ....

I think it is just a matter of time until we see a sort of Kinect controller to go with it. Like a little controller with an analogue stick and a few buttons. Like the Nunchuck. However i doubt MS will make it as it will go against the whole point of the thing. But i can imagine game designers doing it eventually. By doing so will open up the tech to hardcore games.

I would so buy kinect  if it would incorporate this!!!

Well since I didnt really follow much of the kinect stuff I was just assuming they were serious about the whole "no controller is needed" thing

So does this mean the slogan is going to change to    You are the controller..... Sometimes.

Well it was just a joke so......

NAH III

it was marketing ! and a pretty good one if u ask me

It could work for camera control since Kinect mic is very precise for example you could control the zoom of your sniper rifle saying "zoom more" "zoom less", lock on camera on an enemy would be useful too. The grenade thing I don't see it working since you have to keep the button pushed while aiming so you would have to say 2 commands to launch a grenade (grenade aiming and grenade launch.

how long have you known this?

Because I've seen at least a couple posts where you showed no inkling.

One was where you were arguing that 

One was a thread by richardhutnik asking how MS was going to convert kinect users to core users using the idea that nintendo converted casuals to core because of the controller itself. Getting users started with simple motion controls would lead to holding a controller in the traditional way. You said you had no idea, and then defended it by saying nintendo hasn't converted many anyways.

Then in another thread, you said that ps move wouldn't sell as much as kinect because core gamers would stick to the standard controller.

 I stated before  that when it comes to more hardcore games  Kinect (with a controller) and Move will work pretty much the same way.
