If Apple releases a Macbook Air with a faster CPU/GPU + Retina display, I'd sell my MBP immediately and get it. The Air with Retina is, in my opinion, a far superior laptop to anything in Apple's lineup. Reliable keyboard with travel, best battery life, ports, light, small touchpad, no touch bar. It's the best laptop for anyone who's not doing video/photo editing. It's literally what I wanted the 2016 MBP to be.
