45nm-Engraved Xeon Already in 2007.

To fire back at AMD after the release of its K8L processor reported to be faster than current Xeon, Intel has decided to speed up its roadmap. So, 45nm-engraved Xeon originally planned to be introduced in 2008, will be available much earlier: H2 2007. They will be compatible with the current Xeon motherboard. The next generation planned to be released in 2008 will use a different architecture.
So, price of the current Quad Core Xeon might quickly decrease and while higher clocked models should appear.
