Yeah, I'm hoping they will update the Macbook and MBP keyboards as well, since I'd like to have the dedicated media keys.
It's defenitely feasible, as the Macbooks should (eventually) be making the jump to the SR platform in the near future, so those will be updated, and all it really takes is a little bit of paint for Apple to slap on the MBP keyboards.
I'm guessing that by October the keyboards will be updated, along with a Spaces key, mapped to F4 or something like that.
