I agree I like both sports.

I'm all for mixed cards, I think they would be great fun.

At the top level however I hope they keep them seperate.

I don't want to see HBO ppv cards with top fighters like Calzaghe, Paquaio and Pavlik for example have an MMA bout between Kenny Florian and Nate Diaz on the undercard, any more than I don't want to see UFC 96 with Macheeda defending his world light heavyweight crown against Michael Bisping have Joel Julio fighting Cory Spinks on the undercard.

Mixed cards, great for local and smaller events, but no at the top level imo.
