The new D7100 boost of 24.1 MP DX-format CMOS sensor without an OLPF (AA) filter, better ISO Range, EXPEED 3 image processor  same as on the D4, D800 and D600 Full Frame Camera, High speed 6 frames per second, 2,016-pixel RGB (3D Color Matrix) metering sensor, 3.2-inch LCD display that is accompanied by an OLED display within the viewfinder itself and the Twin SD, SDHC, SDXC memory card compatibility.

If you intend to continue using DX body or if you are a new photographer looking for a DX camera, the D7100 is worth a buy in terms of specs, also note the earlier Pro-DX body has never had any updates in the last 4-5 years and the chances for a Pro-DX body release (if there has to be one) looks quite in the distant. The D7100 is available for Pre-order with Nikon 18-105mm f/3.5-5.6G ED VR DX Lens for $1599 and the body alone for $1199.
