September launch for Core i7 "Clarksfield" notebook CPUs?

According to DigiTimes, Intel has updated its launch schedule for several processors. including the Core i7 "Clarksfield" for notebooks:

Intel's three Clarksfield CPUs – the Core 2 Extreme XE 2GHz, Core 2 Quad P2 1.73GHz and Core 2 Quad P1 1.6GHz – will be ready to debut sometime around the end of September and October of 2009, the sources noted.

I'd expect to see these CPUs roll out in high-end notebooks such as Dell's XPS, the Alienware M17 and perhaps Apple's MacBook Pro.
