In my research to discover which 767 aircraft have been fitted with blended winglets, I have stumbled upon this press release from ANA in July of 2008:

http://www.ana.co.jp/eng/aboutana/press/2008/080711.html

In the release, it states that ANA will be getting winglets for its 767-300ER fleet, beginning in April, 2009.

Here we are in April, 2010, and I have found no evidence of any ANA 767 having been retrofitted as yet.

Does anybody know if ANA has postponed or otherwise modified their plans for having winglets on these aircraft?
