Everything's a copy of everything. The only thing making a difference is how well and how 'different' the copy is copied. For example, two people can scan the same document, and end up with different results.
If people have the need to argue about it... they're probably copying that off someone else, too!
Then, if science comes in to play, you, yourself, would be a copy. Yay for mutations.
On topic - Kinect already sucks. There's not much that makes it special. There are some things that should be included with your body being a controller. How about a gun for them FPS, have a little 'realism' to it. A sword for the RPGs. I don't know, they're trying too hard to be innovative. Innovative is good, but that has it's limits.
Pick Up and Play - it's pick up and play for a reason. Reasonable difficulty, decent duration, fun, built on some basics.
And spending $500M on Kinect? It's like Meg Whitman's campaign. Fully loaded, with fail.
As for selling out & demand - Hah. The 3DS has some real demand going on. Chances are, people are going to import that. Now -that- is what you call demand. Selling out is one thing, but getting people to import a foreign version, is another. Just an example, though, since it seems fitting with the upcoming 3DS release, and some recent overexaggerations of Kinect = "best thing ever".
