The only difference between the Eyetoy and the PS Eye is the resolution of the camera and quality of the microphones.  A higher res camera is still not going to be able to turn a 2D image into a 3D map of your body.  It was also released in 2007 and whether Kojima has soured on Kinect or not he would have already been familiar with the PS Eye at the time he saw "Natal" yet no one was heralding the PS Eye as being anything special.

Why isn't something like Child of Eden being done with the PS Eye?  I mean, that's only tracking your hands!  Oh right, because it can't follow your hand movements that accurately and doesn't sense depth.

Again, you would think if the PS Eye could do everything Kinect could do Sony wouldn't have needed Move at all, would they?  Even if they wanted the buttons and increased sensitivity you would think they would release a game or two that could do the stuff Kinect could do just to steal Microsoft's thunder, wouldn't you? 

The truth is developer after developer have said that the things they are doing with Kinect was not possible before, the only people saying "you can do that on the PS Eye with the right programming!" are Sony fans on forums.

Absolutely. Having removed some embedded processing power, Kinect relies more on console's CPU. This means that as long as I/O between device and console not be a bottleneck (but it could be, using USB that has never been a top performing bus), more powerful future consoles will be able to offer better Kinect performances. In the meantime, obviously, SW optimization will be able to better the situation up to a certain degree, but while on the drivers side every improvement will be made available to any SW, on the application side older games compiled with older and less efficient versions of the libraries will be stuck to worse performances unless the SW houses offer patches for them.

In case you didn't know; Forza 3  has "active" steering which is noticable when using a wheel. It would seem as lag to the gamer. In another words, Forza 3 steering is not totally 1:1 as the game driver doesn't always follow your steering 100%. This cannot be turned off either which is why some have claimed Forza is not a  "true" sim.  

LMAO!  I must have been sleepwalking when I typed that.  Thanks for the correction, though.

I didn't mention the Eye, simply that Harminox have said they could deliver the title on PS3 and that from the videos I've seen there doesn't seem to be much use of depth vs how you are moving as a sillhouete, which the Eye could probably deliver through image recognition of how you are moving vs a pre-defined sillouete of what the game expects you to move like.  I haven't seen that many videos, though, nor anything describing in detail whether much depth info is being used or not.

I'm not really trying to guess how they'd do it though, so much as noting the developer has very publicily and clearly stated they could do it - and as they have no reason to lie I'm taking their word as good.  The context of their comments implies that they'll bring some form of the title to PS3 at some point, which would make sense if they can technically do it as it simply means more sales for them and they're third party so why not?

I agree  that Dance Central could be done on PS3 since the game is looking how well you copy the movement seen on the screen. I would think the camera can easily detect "not-A" when comparing to "A" even if only in 2D. Since the game is not copying the player movement but visa versa you don't have a problem with lag either.

 P.S PSEye has already shown it can be used for head tracking even though, unlike TrackIR, it doesn't use IR lights. So it seems there is more than one way to track even in 3D.

From what I've gathered (judging at least by the trailer for Kung Fu Live), the PS Eye scans your body and creates rectangular frames around your head and limbs.  This is, of course, while you are standing still so the camera knows where you're "resting" position is.  Then as you move the rectagular frames move as well, which is where the data comes from.  Theoretically, if you move closer or farther to and from the PS Eye, it should be able to increase and decrease the size of the rectangles, tracking you in 3-D space.

It's very similar to the way the Move works, only with one small globe representing the data for your arms and body's general position.  I would imagine this would be a much easier, as well as quicker, way of tracking you, as opposed to full body tracking.

Yeah what alot of people don't realize that is that the balls aren't only for main tracking but also help with body tracking, because it can tell the ps eye exactly how far you are away and stuff, I doubt the non-move limb body tracking will be as accurate as kinect when moving in 3 dimentions but for near prefect accurate with the globe is an incredibly small price to pay, I can't see kinect working well for any games, I mean maybe a RTS and solitaire and things that are good for touch screen but who would buy kinect for that crap, kinect seems to be the absolute worst choice for a controller yet, move needs better games yes, but the hardware works and good games can be made for it (took a while for good games to be made with the wii too) and it doesn't copy much from the wii other then the basic shape and size, and the tumble(which is in the ps3 standard controller ffs), and I mean what the hell else are the supposed to use for a size and shape, and they even improved on the shape (circular instead of rectangular) 

Kinect will be a strong "casual" device, but the more we know about its strenghts and weaknesses, the more likely it becomes that it will leave the "hardcore" motion market, whatever its size is, whole and undivided to Sony PS Move. Maybe Sony suddenly realized it and this could be the reason why it suddenly looks more persuaded of Move's chances.

I don't see how kinect can succeed as a causal device either, wii pretty much has that market cornered and MS doesn't have anything besides a cheap gimmick that makes the actual games not work well and is incredibly awkward
