Is it possible that the renumbering of the seats on 757-200s and 737-800s shown on seat maps from June on is in preparation for E+? I realize that increasing the numbers at the back doesn't jibe with reducing the number of rows in the front of economy but maybe they are trying to make a clear numeric separation about where regular coach starts on each plane.
Just speculation . . .
