ThinkSecret reports that Apple is set to introduce new MacBook updates soon after the release of Mac OS X Leopard (10.5). Leopard is rumored to be launched on October 26th, and the rumor site expects the new MacBooks to be in the hands of consumers "by the first half of November, if not sooner."

According to their sources, the MacBook update will be a relatively modest update, and simply bump processor speeds. It's unknown if the new MacBooks will adopt the Santa Rosa architecture that adopted by the MacBook Pros in June. ThinkSecret also believes this will be the last Apple hardware revision before the holidays.

These expectations don't entirely correlate with September rumors of a slim aluminum MacBook arriving "soon".

The last MacBook update was May 15, 2007.
