Nikon D-90 SLR 24p HD!

This might be old news to some people but I just found out Nikon just released a 12.3 MP SLR and it shoots 24p HD movies! From the example footage I see here I am really impressed, obviously you shoot through 35mm lenses so that opens up all the doors, how convenient!  the only thing that I’m curious about is audio. Plus its neat to see riding footage at a Seattle spot even!
