I doubt it. There was an 11inch and 13 inch model air and the new MacBook just went right down the middle at 12 inches taking care of the needs of both (people who prefer either size)
Would it be awesome if there was? Yeah. I think if they were streamlining their lineup it would be cool if they did a 12 and 14 inch MacBook and a 14 and 16 inch pro.
But will they? Only time will tell
