Whatever they update is only making an already excellent value even better. What I know, mostly from Willgolf, its the familiar story of first we make something as good as we can and its great but costs a fortune and so then we figure out how to get most of that performance down to a price point. What Eric did with Moab, Dave has done with Raven's Avian series.
Then they come back from doing that and figure out how to make the top end one even better. That's where they are now, trying to make the Elite series even better. So at this point in time the Nighthawk you got is close to Elite and just crazy good value. Would love to hear one, see how much better it is than my Melody. On paper they all look pretty similar but the real black art is in the transformers, and the only way to know there is to listen.
