Introduction
The D5100 is a refreshed Nikon D5000. It retains the swivel screen and does movies.
Also New:
ME-1 Stereo Microphone
Engineered specifically for a D-SLR, and powered directly through the camera
Attaches to the hot shoe and has noise dampening components designed to minimize noise resulting from AF operation
Incorporates a low-cut filter to reduce wind and other noise not already blocked by the wind screen
Utilizing a standard 3.5mm stereo jack, the ME-1 is ideal for the D5100 and other Nikon HD movie capable D-SLR’s such as the D3s, D300s, D7000, as well as the COOLPIX P7000
Available in April for $179.95

Nikon claims Full-Time AF, but I seriously doubt AF works well. it's horrible on the D7000 in video mode.
