If, IF, they do the avionics package on the 757/767 the differences will be reduced further and there was some talk of a combined 767-400/777 category. Delta has reduced the seat lock on the 767, 767ER transition to only 9 months.
there is quite a bit of difference between 757/767; 767-400......the 400 is a completely different type rating.
