Thermals and sustained performance. I expect 10 W passive CPU in MBA body to throttle quickly - I now have 2017 12" MB, and for about 60(winter)/15(summer) seconds of sustained load it's the most awesome little machine in the world, and then becomes a slog.
It has 7W CPU in slightly smaller body than new Air, so I expect Air's performance review to be 'the story about throttling'.
