Until a better product comes along, all the money that is going into Apple's revenue is not going to flow elsewhere. One of the reasons why Apple is doing so great is because so many people are willing to pay a huge premium for their products. If we don't see another company, those same customers will be buying the new version of whatever Apple products they currently own. The same people who buy iPhone4S will be buying iPhone6. Nothing changes except Apple gets more money as they continue to expand.
Its tough to predict a 300 point drop from a company that is in the beginning stages of growth. The years before iPod don't really count because Apple was purely a Macintosh computer company. And we all know how Dell and other computer hardware companies are doing at the moment.
If the TV is a flop or marketed/priced wrong, then 300 is believable. Given their secrecy about everything, I hardly doubt their products will end after iPad/iPhone. And all the existing customers will lure in new customers which continues the circle of life.
Apple may not hit 1000 given how many shares are outstanding and its market cap, but it will be a lot higher than where it is right now. A 100 point increase will may so many people money. It comes down to whether those people will realize profits or continue riding the wave.
