I would of thought after 6 months most places would of sold their existing stock and the 7D's have been coming off the line with the new firmware for about 6 months now. As said, if you get one with the old firmware it's very easy to update. If you get it with version 2.0.0 then you'd be best off updating it straight away as version 2.0.0 had a tendency to create some problems with some 7D's.
