Nikon's D-800: The ultimate adventure camera?

This morning I read the specs on Nikon's new D-800 camera and went ahead and pre-ordered the camera. I have never bought a camera sight unseen, but after reading the video specs on the D-800 it looks like the camera will work perfectly for me. For the magazine work I do I have little need for a 36 mp camera, but the D-800 will work double duty as a back up to my Nikon D-3s and as my main SLR video camera.

Looking at the specs my only complaint is the D-800 has a slow 4 frames per second frame rate (my

current back up camera, the D-300s is only good for 2.8 fps shooting in Raw), but I rarely shoot photos faster than 6 fps. I figure if I do need a little more speed out of the D-800 I can always use the MB-D12 battery grip to get 5 fps or shoot in DX mode and get 6 fps. But if I know I need speed I'll just use my Nikon D3s at 9 fps.

The D-800 I've heard is not a replacement for the D-700, But then two years ago I replaced my D-700 with a D-300s because the D-700 lacked video. When the Nikon D-7000 came out I didn't buy it because it lacked the 9 pin remote inputs for my pocket wizards. So I waited to see what replaced the D-700 and boy I had to wait awhile.

So how will this camera work for adventure shooting? My fast FX lenses, like the 24-70 2.8, are generally too big and heavy and bulky to be carrying on long and remote adventure hike, climb, raft, and bike trips, but I do plan to use the D-800 on just these sorts of trips in full frame mode with FX lenses like the 16-35 f 4, 50 1.8 and the 70-300 vr.

If I want to make the D-800 even less bulky and heavy in the field I might switch the camera to the DX mode. I think the D-800 used with a couple of the tiny DX lenses could make the D-800 the ultimate pro SLR camera and video for adventure shooters. In the DX cropped mode the 36 mp camera becomes a 15.4 mp, that's plenty enough for the magazine work I do. My Nikon D-300s and D-3s are only 12.2 mp! The cropped DX feature in the D-800 (that I never used on my D-3s) is one feature I will seriously consider using in the D-800.

Now I wonder what Nikon has planned to replace the D-300s. A lighter, smaller and faster D-400 would be nice. If that happens that might be the next ultimate adventure slr camera, but if it doesn't come out soon I'll need to get myself a second D-800.
