Panasonic lumix g2 or Samsung NX10?

I'm buying a new DSLR camera, mostly for film making and video, with good manual focus e.t.c. Which one of the two do you think is better. I'm also considering to add 150$ and buy a Nikon D3100. What are your thoughts?

Added (1). Oh, and i'm considering the G2 because of the mic inout it has, which is an excellent feature for film making.

Both these cameras are Mirror-less, not dSLR. Pansonic G2 is better than Samsung NX10.
If size is not an issue, Nikon D3100 of course is a much better performer than any Mirror-less camera.
But you won't be disappointed with Panasonic G2 either.
