Isn't that first pic just a Mac from Colorware?And the second set of pictures don't even seem to make any sense. The screen bezel has no exposed latch points for the physical latches (suggesting a magnetic latch), but the bottom half has a latch button. Which isn't even the same in the three pictures.
I believe that second set of photos have been around for some time as someone's imagined future for the macbook pro. I mean really, I don't see apple incorporating a upper black aluminum case with a mirror-polished under-side like the iPod. That sort of design would find its way into the macbook long before designers considered it for the macbook pro.
