First of the PS1 is just talking about tilt and a little motion sensor. Nothing at ALL like the Wiimote how can you even bring that up as the FIRST motion sensor controller when it barely did anything comparable what the Wiimote is doing right now? You're point #2 is for THE PC...we're talking about gaming consoles so it has no relevance. As for Interlink they're a little company that just wants attention. They are ONLY claiming that Nintendo "stole" their technology. And I just searched on Google and some people are saying its unlikely Nintendo will fork over any money to them since they designed it to be used for a totally different purpose. The bottom line is that yeah Microsoft and Nintendo may have stolen little things in the PAST but its NOTHING compared to the Grand Larceny that Sony has commited over its tenure.
Once again you sony fanboys show you're major hardon for "new technology" or "new graphics". Its not always about that. Who cares what year this technology is? Its working perfectly fine for the majority of games and milions of people enjoy the NEW, innovative method of playing games (in conjuction w/ the nunchuk).
EDIT: Those diagrams may look a little similar but they're not like the motion sensor bar of the or the Wiimote. I mean there are no buttons on that crap for goodness sakes.
