It's not just feasible for Apple to develop new microarchitecture from scratch. Kalamata will license ARM technology. New microarchitecture takes 6-8 years to develop and it's huge investment even for companies like Intel, Amd and ARM.
Currently only Intel and Amd have high end desktops CPU's. ARM is likely enter as third with ARM architecture that Apple is licensing, but it will have relatively low performance.
Apple will likely take a hit in workstation markets for CAD and image processing application market but they are in the position to gain a lot in more common use cases if customers get better power/performance ratio.
