It's got a 15.3-megapixel sensor with a standard ISO range of 200-6400, 6FPS bursts, and yes children, full HD video recording, which would make it Nikon's first to shoot in 1080p. In other words, a pretty solid bump of the current D300, the main new hotness being the addition of full HD video.

That is, if this screencap isn't a Photoshop. The specs are a little different what was rumored a few months ago—but both are pretty plausible. Even if it's a fake, the noise is starting to build, so there's likely something to the D400 whispers, since Nikon's not the best at keeping secrets. [Nikon Rumors]

Nikon Rumors got these specs as anonymous tip—anonymous comment, actually—so the standard caveats apply, BUT they do look fairly plausible, and fall in line with what Nikon's been up to lately. The most significant update is the addition of the rumored 1080p 24fps video recording, a whack back at Canon's 5D Mark II, whose video capabilities have blown us away again and again. Of course, we'll have to wait and see how good it actually looks. (Here's why DSLR video is finally happening, if you're curious.)

The rest is fairly expectable with a mix of current Nikon features and new specs—14.8MP DX sensor, but I'm hoping it'll be more D700-like in the noise department—and $2000 seems about right as the price tag, though $1800 would be more aggressive.
