Quoting Bringiton (Thread starter):
Why does the 787 not have winglets

It does have winglets. It uses the blended wingtip... which give the same effect and is the same used on the newer 767's and 777's and the new 747-8

The 787-3 will have the more traditional "winglets" that flow up from the end of the wing. The 787-8 and 787-9 (and probably any larger variants) have the blended wingtips that cant back parallel to the wing ala the 764ER, 772LR, and 773ER.

The 787-8/9 and 747-8 use a style of blended wingtip that was actually pioneered by Fairchild Dornier before they went defunct. It's considered more advanced than the flat wedge-like wingtip on the 777LR and 764ER.

And as others have said, the 787-3 has a 737NG-like vertical winglet to reduce span distance and allow the aircraft to fit into smaller gates. It will also provide more lift on lower-speed take-offs and landings.

The 787-3 has 737NG style winglets while the -8 and -9 have a type of raked wingtip that flex in the air that almost look like winglets. All three are going to look fantastic!
