some early users are happily shooting movies with the new Nikon D90 and what I see so far is not that impressive at all...

It's actually a pretty sad performance, shaky, no precise focus movement. It just looks that AF lenses are not perfect for this kind of stuff and it would greatly benefit from a tripod or in body stabilization.

Which I'm not a huge fan off, just one more thing what can break in the camera...

well time will tell
