1. Motion sensing did not begin with the wii, you could use motion controls like the Wii on the Sega Dreamcast with the fishing rod using it for both tennis and the fishing game on Dreamcast. So, if Sony ripped off Nintendo, Nintendo ripped off Sega. Sony's use of motion control is not like the other consoles though. It is used very little unless you want to play games like warhawk and lair with it on, it also does not use the controller of the same form.
2. Home button was on PSP before it was on the Xbox 360.
3. Seriously, what are they supposed to do? come up with another way of communicating over a game besides text messaging, voice chat. Come up with another way to download content other than an online store that is feasible. and once again MS copied the idea of online from the Sega Dreamcast and yes i do think sony would have attempted online this gen, if MS had never been around. Now PS2 online, i don't think that would have ever happened.
4. Rumble no doubt was a rip off of N64. However, Sony improved the idea of the analog stick and the dual analog stick was something that was never done on a console til then. D-Pad and shoulder buttons. Once again, what are they going to do, because whatever else they would have done would have probably flopped hardcore, espeically if you are having to revert back to using only 1990s technology.
5. No clue about this one.
