Very obvious next step is to release 15" or 16" variant. It would put nail in coffin on cheap PC market. But would also cannibalize their own air/pro sales.
Sadly, "nail in coffin" is an exaggeration. Though the press would be throwing that phrase around. With plenty of dire-sounding quotes from cheap PC manufacturers.
Limiting cannibalization wouldn't be hard. Just load up a Neo, a 13" Air, and a 15" Air on the Apple web store's Compare page - a 15" or 16" Neo would be the "obviously lesser" laptop by 90% of the metrics.
My bet is that Apple has prototypes of the larger variant, and is waiting to see how the situation develops.
