Well, Pentax have announced their new DSLR, the Pentax K-7, and rather than just repeat all the specifications that you can easily find all over the internet, I thought I'd point in the direction of this Pentax K-7 video on Youtube.
Note autofocus in video mode (something none of the other DSLRs can do), in-camera HDR (with three exposures), 5.2 frames per second, full weather sealing (again!) and cold-proofed down to -10 degrees celsius. Various other little gems.
I'm really looking forward to trying this camera out, and I think it will be my next upgrade. My K10D has served me well, and I think this new K-7 will be a huge improvement.
