What is the VERY best professional digital SLR camera for outdoor photography as well as portrait and weddings?

It's not about megapixels or iQ... it is about controls. How can a PRO afford to enter the menus to change something that's really important for him for that photo, like metering, or type of AF?

That's funny... because there are no pro cameras. But there are cameras that doesn't limit that much the photographer. And that's what pros look for. In the IQ department... even a D40x would do the job. But... what about everything else? Is it cool to have an only 3 points AF, with no high precision sensors? Is it fine for you to cannot use lenses like the Nikor 50 primes, because of the lack of screw drive AF?

That's what pro cameras are about: make the limit the photographer, and not the camera.

And for that... with the controls that the K20 has, with the lenses that Pentax offers, and with the weather sealing... the K20 is up to the job. In the IQ department... so far it's the best APS-C camera that I've tried between sensitivities 400 and 1600. AF is improved, but in low light its a little slower than Canon or Nikon, due to a double check algorithm... (it doesn't fire until it checks twice that it's in focus, so actually it's more reliable... but still slower).

And the benefit is that with Pentax you can use all the lenses Pentax ever made, with stop down metering that it's the simplest of every manufacturer (just push the green button), also very old non K mount lenses, via adapter... and the real benefit... is that you can have Shake Reduction with ALL those lenses... as well as new ones... and is as effective with a 45 years old takumar, as a DA*300 F4.
