The performance of the mid range professional DSLR was a bit disappointing for me from the performace in low light to their AF system. One interesting new variable is MP/cm pixel density. DSLRs (~ 2 MP/cm), higher end point and shoot digital camera's (~ 20 MP/cm) and range-finder cameras (~ 2 MP/cm) have a lower density than the cheaper cameras.

The new Leica S2 is an interesting leap with a 37.5 megapixel CCD, a larger sensor (56% larger than 35mm full-frame). http://www.dpreview.com/news/0809/08092301_leica_s2.asp

With higher MP, you will need higher optics or switch to medium format cameras.
