I'd love to see UFC here in Moscow, but there're no russian names yet, only prospects seem to emerge right now... if they could somehow make Fedor return to fighting, then things would be interesting. Even though, he would get crushed by the current elite.
There are quite some Russians to seep into the UFC at the moment. Not big names yet, but so far they are mostly successful, so we'll see what will happen in the future. Their Combat Sambo seems to be a pretty good base to start MMA.
