It's hard for Nikon to fight Canon on video, so they're fighting with what they know: photography. Nikon's new D7000 packs a 16.3-megapixel sensor, 39-point autofocus, dual card slots and ISO up to 25,600 in a $1200 camera. Hot.
A successor to the D90, the D7000 has a new 16.2-megapixel sensor, which Nikon says has "low-light ability never before seen in an DX-format (APS-C) camera." Bold words. But they back it up with a normal ISO range of 100-6400, expandable to ISO 25,600. And, given the lower pixel count than the 18-megapixel 60D (which reuses the same sensor from Canon's lower end T2i), it seems reasonable to assume that D7000'll win out in low-light situations.
