I posted the following on the latest MR article claiming the new part numbers said to be for MacBook were actually for a new cinema display. Thought this would be relevant here, too:
There will be no MacBook update because the new MacBook Airs will be called simply "MacBook". The white MacBook will be dropped- and, no, I am not somebody with a weird fixation of wishing the white MacBook were dead because I hate what it looks like/ thinks it serves no purpose. In fact, it was my first Mac notebook and I LOVED the MacBook. I still like the design and love the white - however MacBook Airs were not dubbed "the next generation of MacBook" for nothing. Apple loves streamlining product offerings, and this only makes sense. I would also not be surprised if the 13" Pro bites the dust when the Pros are redesigned in 2012. I'm ready for the thumbs down, so shoot, but don't be surprised if this is the case.
