I can't speak for DWB, but I can easily get sharp images at 1/30th with the D700 + 50/1.8. With my K20D + FA50 I could go to 1/15th or 1/8th with care. But that's bad technique for static subjects. If shutter speeds are going that low, I really should be using support.
Another problem with low shutter speeds is that my subjects (people) are usually moving. So even 1/30th is too slow to freeze any movement. I really enjoy that fact that ISO3200 on the D700 is better than ISO800 on the K20D. Less noise, more dynamic range, and more shutter speed or aperture, take your pick.
As far as dual systems - once I got my D700 I found less desire to use my K20D. I sold it and all Pentax AF lenses after two months of non-use. I kept the MF lenses, if I ever really desire to use them I'll probably get a Canon 5Dmk2 for that.
