Nikon has it right with the D3s. Canon's new 1Dx is promising too, although it is 18mp vs the D3s 12mp.
Interestingly, myself, Troy & Andrew all came to similar conclusions today about a very well known macro photographer's images, who went from a 20D to a 40D 2 or 3 years ago. Said photographer will remain unnamed.

Hi Dave-yes I have thought thst 10-12 mp is enough on crop sensors.Just to clarify my observation is not running Dennis's images down-these and the others from the 7D are of a high standard.My point was that I felt that when he use to post the images from his 40D and 400L /100 mm macro.They were better-they had more 'punch' and you felt OMG when you looked at them.
For example the image of Eastern Water Dragon eating grass hopper,and the macro images he posted around that time,were IMO of a standard that had far more impact on the viewer.I just wanted make that point clear-andnot get into trouble.
The newer cameras are far more complicated than a few years ago,they take time to learn how to manage.Jason (Kopati) mentioned he was having a learning curve to understand getting the best colours from his new 7D.
As an owner of a XXd and XXd camera.My next rung on the EOS ladder is a Xd either a 7D or or a 5D so,I have to make observations and engage in dialogue about such matters-the is not a critique of Dennis's fine images.
