When asked what he thought of people saying that Sony stole the PS3's motion-sensing controller idea from Nintendo's next-gen Wii, Harrison replied, "In some way, I understand why people are saying that, but it's a bit dumb, if you can forgive the expression."
...
"When we [Sony] brought PlayStation to the market in 1994, we introduced real-time graphics in 3D for the first time," Harrison commented, apparently dismissing SEGA's Saturn. "When Nintendo released N64 in 1996 and it also used real-time 3D graphics, did we say: 'Nintendo stole our idea!'? No, of course not. Such innovations are made possible because of the combination of technology, cost and manufacturing capacity."
Harrison also clarified that the PS3 controller design was not a last-minute decision, as some suspected.
"We've been working on that [motion sensitive controller] for a long time," he said, "and Nintendo has no doubt also worked on similar, if not identical innovations for a long time -- that's normal. That's technology. The difference between our strategy and everyone else's is that our controller, the PlayStation Dual Analog Controller, is the de-facto standard for videogames.
"I'd estimate that if you include controllers of the same shape from third-parties, more than 400 million were sold world-wide. That means we define the standard for the man-machine interface for games. Now we added an additional dynamic; freedom of motion."

Such spin... and lies. I thought I had read an article that stated most developers admitting they did not know about the "six degrees" controller nonsense. Wasn't it someone on the Warhawk team that stated it?
