I have a Canon 400D and am thinking of upgrading to a full frame, namely a D5. I am reading that the D5 is two years old and may be replaced with a new version soon and some people seem to be waiting for that upgrade. I am a relatively new photographer and am not sure I know enough to benefit from many possible upgrades. I'm certainly in no hurry anyway; the cost of the D5 might drop just before the new model is introduced.
Any thoughts or guidance from people who have "been there"?
