None of those do video and compared to the 5DmkII and GH1 it appears to be relatively cheap.
Video was probably not the top priority in that choice of alternatives to the D5000.
But if video is important, there is no need for the 5DMkII: the new 500D does video at a price similar to the D5000. Also, the GH1 body will probably be in the same price range as those two: the US$1500 price is for a GH1 kit with the video-adapted 10x zoom, a lens expected to retail for about $900.
