dpreview.com Hands-On Nikon D300s Preview

"Not all of the changes made to create the D300S will be immediately apparent from looking at the specification sheets. Thankfully Nikon has loaned us a D300S which we've pored over and peered into, in an attempt to get to the bottom of the less obvious changes that have been made to its APS-C flagship."

dpreview.com was lucky enough to get their hands on the new D300s prior to the official announcement, and they've written a small article with some of the changes. I'll be interested in seeing if the video on the D300s is noticeably better than the video from the D90 - it should be given the superior sensor on the D300s, but one never knows...
