I currently have a Nikon D60. I'm at the point now that I shoot in Manual all the time and the lack of 2 control wheels is getting annoying. Should I spend the extra cash and upgrade to the D90? Or should I wait till Nikon comes out with something that takes better HD video? I just don't want to spend the extra money, and then have something better come out in less than a year. Opinions? Should I wait it out?
