Some questions about the exits in the back given this seems to be the only thread on this bird.
Seatguru shows 26DEF as exit row on the right side, but the Delta.com seat map (and through the GDS) doesn't show those seats existing at all, and instead lists 27DEF as preferred exit rows.

Is there another configuration of this aircraft? Does anyone know if the exit is really 26 or 27 (on the right)? Obviously SeatGuru's track record isn't great, but on the other hand, most airlines put at least 2 seats near both exit doors, seems odd to not have anything there (even assuming the map is not to scale).
