"I don't know what [Sony's] decision making process is" if we are talking about move and eye. well I have been watching this with great interest for some time.  sony made the eyetoy, and released it.  they struggled to get third party support and couldn't get it and even the first party's didn't make much.  so the r&d team started working on the interface. they figured that getting the device to recognise objects could allow for more fun and more control for the user.

they continued to play about with it and figured you would need to get it to do really cool stuff they would have to look at depth, and there is also problems with lighting and getting a round the need for a object.  sound like anything to you.

eyetoy demonstration a lot of facts about camera development, depth is about 5 mins in.

then microsoft buys over 3dv systems, the technology was beyond there reach and there rival was likely to use it against them but they new the disadvantages and they new controllers could get around it.  by this stage nintendo had its controller released but (i am assuming) there was away around this, probably the way it works.  it would give them the advantage of having the controller and the camera tech.  i feel they were forced to retreat from project natal, sony says they looked down that road and said it wasn't worth the hassle (not exact quoting).  so now they take the advantages of there work in all area apart from depth which they need a controller for and are releasing ps move.

this is how i think they got to a controller. 

^ All that means nothing, really. The Move and sub-controller is a blatant rip of the Wiimote and nunchuk. Doesn't matter how many youtube vids you come with.

did you read what i said in the last paragraph it basically agrees with you, and sony mentioned nintendo at the gdc thing because they are very similar pieces of tech

Well if you compair adding an analod stick to adding a button why not 3 or 4?  I think going for two was a big thing as has become pretty standard in most controllers.  How about the location of the 2 nitendo had them off set before but for the classic controller went to the parrallel. 

ot  It's funny how this is about the sixaxis and the controller not having rumble then having it notthing to do with the new controllers.  Some things though if only one company could use it there wouldn't be much of an alternative.  keep hearing people mention the dpad.  Since the dpad came around all companies use them just not the + like nintendo owns.  sony takes the middle out others have added the full circle around it or bysected it.   For those complaining about the ps controller being like the nes one, who then went off an did a weird controller when they didn't need to?  what was up with the n64 controller?  at least the ps controller from the snes one was progressing making it easier to hold adding the two analog sticks two shoulder pads per side. 

Relax, Nintendo.

You're not the only one in the industry.

this article must be 3 years old? there talking about the sixaxis not move

^ Still applies today though.

Not really. There isn't much evidence that either Sony or MS would radical change input on their own. And the types of changes that were made could of been anything. If there was another innovator they could of introduced stuff like capacitive handles or what not instead. The point is their inclusion had more to with designing rather then just implementing evolving technologies which is something ever console manufacture has to do.

As I said look at the Dual Shock 3 it is the same as the original Playstation controller with the inclusion of technology used by Nintendo and Sega. That is the sign of a company that will not take risks. MS entered fully planning to integrate Online gaming they hired a Sega VP to do so beause of the Dreamcast. The Controller is based off the Dreamcast controller and so forth.

There is nothing to show that with Just Sony and MS you would have had controllers evolve at the rate they did. Where Nintendo at least changed their button layout for these least innovative controller. the other two company's appeared content.

Edit: The Amiga was a legendary computer system that was way ahead of its time. Its biggest contribution was the implementation ofColor magic(16 bit color) which was developed by an Israeli company. Its sound software was off the wall for the time, Lightwave made all other computer animation programs look insignificant and it was the perfect example of how a closed Hardware software system can reach heights above that of a closed system in terms of performance. No other computer system has come close to replicating that truly walled garden approach.

that said the Amiga CD32 was total junk but now is a collectors item.

It was junk. I need to finish Simon the Sorcerer.
My point was these changes would happen if not a bit (or lot) later.

Actually NEC was the first with there turbografx 16 cd add on in 1990 I think it was and then sega in 1992 so sony definately wasn't the first on that.
