Nikon has a new image processing engine (maybe called EXPEED 3?) that will be able to deliver some insane frame rates and video capabilities. This new processor (or a light version of it) will be included in the new Nikon mirrorless camera. No word of possible implementation in a new DSLR camera yet, but obviously the D700/D3s replacements will be good potential candidates. It is interesting that Nikon decided to first introduce this new chip with their mirrorless camera (unless there will be a new full frame camera announced between now and September 21st).
You can read more about the current EXPEED 2 processor here and here.
