Buy a camera for the lenses you choose. Not lenses for the body you choose.
Bodies depriciate and need to be replaced more often. Nikon bodies may be ahead now in many areas, in three years Canon may move ahead. They seem to go back and forth.
IMO canon has the better glass for what I do.
I am not sure what you mean by Nikon lenses more expensive, I don't think that is the case overall.
