Which is completely against every rumor we've heard. (Not just a month difference like September-October.)Expect to see new macbooks in the first quarter of next year.
Well I've got bad news for you.And at any cost.... the specs would be same for an upgrade now or in Jan since the montevina is the last update intel is providing its current Core 2 lineup! After this... its gonna be Nehalem in mid 2009!
The latest signs point to regular desktop and all mobile variants of Nehalem coming in Q4 2009 for quad-core and January 2010 for dual-core.

We may see one more 133 MHz Montevina speed bump in mid-2009 before Nehalem.
