Any other comparisons aside, BMW kept the same design for about 5 years (or more, for the 3 series). In car years, that's an eternity.

My thought is product recognition.
 
So we are looking at a major redesign in January

MacWorld is in January, so it's possible. I expect the MacBook Pro to at least have a redesign with Penryn and maybe they should go back to Titanium with a better latch or have black anodized Aluminum with the new redesign.
