I think the whole 'pro-user' description needs examined a bit. Tons of developers at companies use macbook airs which are far less powerful than the newest laptops.
Ex: Rob Pike uses a macbook air. Is he not a professional?
There's a huge range of needs even within the pro user camp and I'd posit that the majority of them will be well served by the new Macs. If you're doing game development I'd argue Apple hasn't made great machines for you in the past so I'd expect a continued miss on the portable VR front as well.
For those that are doing visual work - are current generation machines actually not powerful enough?
