Apple will announce a Developer Transition Kit at WWDC, which will be available this summer. The DTK will use an A12Z (the current iPad Pro SoC), inside a Mac mini chassis. Or, I think less likely, an Apple TV chassis with added I/O.
I don’t think it will be a laptop: that would require full power management to be implemented, would be more expensive, and would result in battery life figures for semi-prototype hardware being reported all over the press. That’s really not how Apple rolls.

Yep. I agree with this all the way.
