DX format for pros stays

For skeptics who think DX is a dead format for pros...listen

I strongly believe Nikon will continue producing advanced dslr DX format. (D400)

the reason is that there and there always be some advantage of DX over full frame on some points (Nikon old argument stays...image circle, free telephoto, less vignetting, cheaper).

I keep D300s still fine and waiting D400..I own several DX lenses so i let pass d800
