Well, the isight is now dead and Quad-Core processors have debuted. Is it time for a new Mac Pro, I believe so. Now this is just speculation but wouldn’t it make sense for Apple to come out with a second configuration that is more expensive than the current Mac Pro that features 8 Cores inside.
There are also some rumors out there that Apple will be revising and possibly dropping the price of its monitors. Adding an isight camera to the top of the display and since Apple has seemed to be starting to make things a little bit better bang for your buck then it has in the past with the drop in price of the iPod. I think it would just make sense for apple to drop the price of its displays.
