This are all speculations, feeded by rumors and the latest PC laptops. case Apple always said the 12” Macbook is the “future of the notebook”. So it’s clear that the new Pro`s will look like bigger brothers of the 12”. The thing I like the most of the 12” is the color! Space grey on a Macbook looks awesome! It’s darker than the normal aluminum unibody. They should just add more than one USB-C port… So I hope the new pro will be also available in space grey and perhaps in pink, sorry rose gold :-).
