According to HKEPC there is a rumor that Intel is going to release a Merom Core2 Extreme, running at 2.6Ghz (and later this year also at 2.8Ghz) with 800Mhz FSB (together with Santa Rosa?) for $750.-. The processors are supposedly targeted for extreme notebook lines such as Dell's XPS line. Perhaps also for the MBP line?
