Pulled these images off a post from appleinsider. Looks like there are leaked images of the new design of Mac Books. They apparently are made of the same material as the Mac Book Pro. There are rumors that apple is combining the Mac Book and Mac Book Pro into one line of books. Of course there will be an entry level and then of course a higher end model but the same chasse. Just like now, there will be the ability to do slight upgrades and so forth.
The rumor is that there will be an event during October, I am still hoping that not only with the MB and MBP be updated, renewed, speed bumped, but also the MBA!!!!
Keep those fingers crossed!
