I have included much of the same information in the topics introducing the new cameras. I am starting this particular topic to discuss converting the Subal housing for the D200 for use with the D300. Here is what I have noticed, read and surmised so far.
1) It may be necessary to make a new mounting plate to keep the camera properly lined up.
2) The larger screen on the back of the camera has necessitated that the controls be moved towards the perimeter of the camera.
3) For my personal use I would not mind having the screen on the housing back be slightly smaller than the screen on the camera. So, for me, if the Subal D200 housing back can be made to function I would like to use my existing back rather than buying a new back for perhaps half the cost of a new housing.
4) Best of all worlds would be if the back could be switched from the D300 back to the D200 with less than 1 hour in the field. Then we could keep the D200 camera as a spare body for backup use in the field.
5) As I posted on the other threads This morning when I first heard of the D300 into I Got pictures of the D200 and the D300 camera back and in Photoshop I painted the outline of the new display and, the new control locations of the D300 onto the D200 back.
