What Can Stop Apple?

What can stop Apple from going higher? Not even Steve Jobs retiring or his passing away will stop Apple in the long run. All the bad news that comes out about Apple is outweighed by the good news. Even if there is bad press, it doesn't stop the stock price. I think that Apple stock can  reach as high as $580 for the reason that IPad 3 is being released soon and hopefully the release of the IPhone  5 will follow. I think that Apple stock can't go higher than $580 without making a new product.
