Well, no, Nintendo was the innovator as they were the first to come up with the idea of implementing this type of technology in a MAJOR WAY onto the console scene. Everyone knows this technology has been around for 10+ years, it's no real reavolution except in the way it's being implemented.
As soon as Sony found out what Nintendo had done, they threw away the boomarang controllers and "mimicked" Nintendo in a very lame way. If you look at the timeline of the last year, it's obvious that Sony did this, but really, it's not a big deal considering the differences in both technologies and the fact that neither company came up with their respective parts first (in the grand scheme of things).
QED
