According to an anonymous report, six new Mac placeholder SKUs have appeared in Future Shop's inventory system. While we've been unable to independently verify this at this time, the placement of early "placeholder" part numbers is consistent with inventory practices of some major retailers.
In February, we saw MacBook Pro part numbers in Best Buy's systems about 3 weeks before the release of the new MacBook Pros. Future Shop is a Canadian subsidiary of Best Buy.
Apple has been rumored to be planning new releases for their laptops (and maybe iMacs) before the holidays. The last rumored date pinpointed October 14th for the launch.
