I have now just got my Nikon D90. Based on what I've seen posted on the internet and my own experimentation with the D90, I'd have to say that if you're being paid for doing a professional video job, or if you want the highest quality video from which you can grab sharp, 2MP frames, the 5D Mark II is the way to go.

That doesn't mean that the D90's video is bad, as for my needs, they're more than enough.

But looking at Nikon's choice of bit rate, encoding, compression algorithms, etc seems, to me, that Nikon meant to target the D90's movie mode for the "non-pro" crowd.

Good luck with your decision!

i think my best bet is to wait until next year and if they do not come out with something better i will probably go for the nikon . its cheeper then a letus dof adapter . thanks for your comment
