I'd suggest going to a store and taking some cameras in hand. Get the one that feels good to you. I personally (just my opinion) don't see the real need for "pro" cameras unsless you are shooting sports, or certain weather situations, such as in a rainforest, or need more than 6mp res. Most of the entry levels have just about everything you would need, and if it doesn't, there's likely a workaround.
So, I would look at entry-level or one step up, and get some good glass with the extra money you have. Bad glass on a "pro" system still won't necessarily beat top glass on an entry level...
Just my $.02, go ahead gearheads, and beat me! I love it!!
