So not theoretically, but apparently it already does support multi player detection.

I agree.  With the popularity of Wii, now all three gaming systems seem to go into motion control, but at the same time some games are meant to stay as the way it is.  RPG is definitely one.  Though ARPG like Monster Hunter may benefit from motion control. 

@bobobologna,

I can give you my personal opinion with some example.  For instance, Soccer game.  Wii mote does not allow you to use legs and with the it is made, it would be difficult to do so.  Now comparing this to PS Eye, yes PS Eye can detect leg motion, but NOT in 3D.  So you won't be able to kick the ball by standing in front of TV, but you can do so on the side way.  Now will this change with New PS3 motion control?  Hard to say.  As Sony's tech did show incredible level of precision, but did not show whether such can be applied to legs or not.  But this is just an example.

And how would you move in the soccer game?  How would you control the camera?  Would it be a third person soccer game where you control a single character and have to dribble an imaginary ball while using 2 analog sticks to move and control the camera?  Would this make the game BETTER than other soccer games?  It would be a nightmare to control, while also dribbling and shooting/passing an imaginary ball with no tactile feedback all in a living room where most people probably have a coffee table.

So please, give me more details.  Please think about your game before responding.  I'm genuinely curious because any practical gaming use of Natal escapes me.  All I can think of are mini games/party games like Wii Sports and those Eyetoy games.

Moving in soccer game depends on the actual implementation, but one I can see is side movements by actual body tracking, dribling (forward movoment) based on the depth info.  For example, when the program registers you upon starting of the game, set it as natural/stop position.  If your whole body or one leg is more closer to the camera, have the character drible to the front and so on.    As for camera control, not much difference from many of action games.  For instance,  there are tons of games that does auto camera.

needeless to say part of the benefit is Shooting or Passing.  You can actually make the actual soccer moves there.

So in my opinion, if you are looking for virtual sports experince by moving your body, there is definitely potential there.

Other game example would be martial art game.  Aside from Wii Sports boxing's poor precision, Natal in therory again should allow one to do kicks.  Perhaps if depth information is there, they may even be able to recognize spinning kicks.  Difference from Eyetoy Kinetic Combat is you can do tihs more natural way i.e facing against the opponent rather than side ways.

Oh, and as for your opinion about no tactile feedback, I agree that is next step in this virtual reality motion control technology. But remember there are many people out there now really interested in moving there body to play games. Wii simply proves this. So your argument about no tactile feedback, coffee table no space part is simply sounds like your preference.  Besides, do you think the control vibration gives anywhere near the actual kicking soccer ball?  Personally, I'd sacrifice the hand vibration, which really isn't any real feedback for soccer game to begin with, for actually moving my body as if I play soccer in comparison to using my thumbs to move characters and push bottons to shoot ball.

As I stated above, motion control is not for every genre of game and I don't think it means to replace every single games. But rather introduces whole new way to enjoy game. For instance, when you want to play Soccer or do martial art, but just simply you don't have those skills, place to play or friends to play, or time to play, Motion controls would give those people the answer.

Forgive me if I misunderstand you, but the way you have phrased your statement, I somehow got sense that you are not much into the whole body thing. And that's reasonable and understandable, but if that's the case, I don't think you will never see Natal as benefit.

Just as if you say "I hate listening to music", Tell me what's good about Ipod?

But otherwise, I'm willing to make a discussion with you to say at least why I am excited about Natal or PS3's new motion control.

Did Sony allow anyone from the press to try the PS3 Motion Control?

the ps3 ice cream cone is nothing more than a wiimote with motion plus. sony is doing nothing that hasnt been done before, either by them or Nintendo. The difference here is Nintendo will always do it better than them because almost all of their games support motion sensing.

OK so I assume Sony did not let the press try any of the demos they showed on stage. Also Sonys doesnt have anyway for you to move your character. Now I assume they will come up with something just like I assume MS will answer some of the questions regards to buttons,steering wheels, props, etc.

@thx1139

As far as I know, I don't think sony had let anyone tried the demo, but on stage demo seemed very well shown for its ability.

Regarding to character moving, I thought they have demoed this with those FPS thing. The presenter moved around and gun followed it, along with various angles.

But if you are specifically talking about the demo with shield & sword, I agree that the character's body did not move. This may or may not be the issue as I have seen with EyeToy game that they can map body movement at least in 2D. So PS Eye alone should be enough to get body movements in 2D.

But depth info might be issue and in fact, this might be where Natal could demonstrate its superiority.
