More and more it looks to be that the 3 cameras stated by Nikon to be released in 2012 were the D800/D800E, the D600 (full-frame entry level) and the D5200. It appears that they are leaving the DX (crop sensor) playing field wide open to Canon. So far there has been no semi-professional DX body released or any rumor of a D400 (a replacement to the D300s) floating in the ether.
What does that mean for professional/high-end amateurs with no expected D300/300s replacement in sight? For some it may mean a costly DX lens dump (for those who have been shooting with DX lenses such as the AF-S 18-70mm f/3.5-4.5 and going to a fixed aperture f/4 lens or expending lots of money and going to the storied 14-24mm f/2.8 and 24-70mm f/2.8; and saving for a full-frame D4.
As of right now it appears as though Nikon is not planning any more releases this year and from the looks of it, DX is being relegated to the entry level playing field. Hopefully I'm proven wrong and that it doesn't mean that Nikon is finished with DX in a professional sense. But it feels as though there has been a push by Nikon to guide the high-end amateurs and professionals into full-frame as a standard. I guess you could say I'm a stubborn hold-out but whether a full-frame upgrade right now is necessary, we'll just have to wait and see.
