Yes you are right Nick. I just did a little search on airliners.net, and seems like quite a few have them fitted now.
Oh, and I just found out (also on a.net) that all the ANZ 767s have them now with ZK-NCI the last to be fitted out.
But i must admit, they do look quite attractive on the 767s just as much as they do on the 737s and 757s.
