Totaly unreliable rumor. Doesnt make any sense that Apple (or any other manufacturer) would make such a gamble.
On the other hand, I dont understand all the freelance guys here who say that they want to keep their machine for more than a year. I hope you know that you are WASTING money doing so? Always sell the system once its one year old and get a new one. Thanks to accounting principles based on the life cycle of pc, you actually MAKE money selling and changing computer once a year. Its mainly based on the fact that computer lose book value at 30% while mac's value drop much slower.
Talk to your accountant and if he doesnt agree with this, you better look for a new accountant...
