There was virtually no change between the 2010-2011 Nox (couple of new paint colors, flex fuel for the V6) and according to a guy on another forum that works at the CAMI factory there won't be any real changes until 2013...but even then likely to be cosmetic. If you can get a good deal on a 2011 there doesn't seem to be any reason to wait. (unless someone knows something I don't of course)
