767-300ER will also get full-flat seats!! And the English PR also says
A foremost highlight of the renewal is the fully flat beds in Business Class arranged in an innovative layout that offers every customer unobstructed access to the aisles.
So I wonder what layout it is
Also no mention of 787 which is odd considered the 763 is getting new full-flat long-haul seats too...
