Sure. Sony patened a mation sensor..
So did Nintendo.. And Microsoft did
that too (loooong ago). Neither
company came up with any of the
motion controlling technology.. They
just use it..
It's just very suspicious that sony
showed their motion controller right
after Nintendo did. (Even the PS3
developers didn't know anything about
is).
Anyways.. I'm getting all the systems
within a few years. So i couldn't
care less :D
