For starters, the D3200 got a much newer DX-format CMOS sensor with double the ISO performance (to 6400, up from 3200) and the same Expeed 3 Processor that you get on the incredible Nikon D800 (Which we're giving away soon!). It also shoots an improved 4 frames a second and got a whopping 921k-dot 3" LCD screen, up from the D3100's older 230k-dot screen.
Autofocus remains the same, with Nikon choosing to stick with the 11-point system available in the D3100, and it also has the same guide mode as the previous model.
The D3200 also shoots 1080p video at either 24 or 30fps, has an HDMI output and features a new 3.5mm microphone input jack.
There's also the option of a $60 wireless adapter that will allow you to connect your D3200 to mobile phones or tablets, giving you the ability to access the camera's live view and control the shutter from your Android or iOS device.
Finally there's price: the camera, bundled with the standard 18-55mm VR kit lens, retails for $700. No word yet on a body-only price.
Oh yeah, and it's also available in red.
