Intel Moves Nehalem Launch Forward To September 2008
 

Originally scheduled to launch in November or December this year, Intel's Nehalem-based Bloomfield processors will now launch in September along with X58 chipsets, sources at motherboard makers have revealed.

However, the sources pointed out that CPUs and motherboards will not officially appear in the channel until early October.

I'll believe it when I see it given that the rumour was that the MB manufacturers were struggling with the 6/8 layer PCBs required for X58.
