God i hope they don't mess with the keyboard.
They'll probably add the new thinner one from the 12" MacBook Pro. Apple usually learns new things from other products and applies and perfects to older lines upon refreshes and vice versa. I have a feeling the redesign is going to be pretty thin and still retain the portability and the size and speed with a better iGPU and dGPU and of course Skylake. But I think they will go Broadwell soon and then update to Skylake since the architectures are in the same 14nm process.
FYI for anyone else, Adorama is a good retailer. They're competitors to B&H and B&H is a superb company.
