1) sony had a ton of work done on motion controls before someone even thought of the wii (and kinect) it was like the combo of the two but back then in ps2 days the camera wasnt good enough and the technology was too expensive (and still is e.g. kinect, trackir) so they didnt do much with it.
2) wii u seems like what ps3/psp already did with lair years ago. but again the technology wasnt good enough (in terms of graphical power and analogue sticks. with NGP its possbile so just because they enter the market at a feasible time people will think they copy nintendo when the fact is they know the right time for the right technology.
