Your response is rubbish. There are Westmere Xeons. Other manufacturers are using them:

6 cores which cost more doesn't count as new refresh technology, it counts as something they may add to the lineup as they did the 3.33Ghz W3580!
Im well aware what GPUs/CPUs are available now, however as a 2009 MP owner it's great for me because my machine has lasted longer than any other MP!
No use moaning about it, Apple will update it when Apple wants to.
