It won't happen. I believe Kitsyn could have had one as well but didn't. All in all, out clauses in Russia are very rare. The only way out of a contract there is if you suck ass and the team lets you go. And that won't happen to Nikolai.
Not true. Evgeni Kuznetsov, a prospect for the Caps has one written in that if he is traded by Chelyabinsk he will become an "in conflict" player and can sign anywhere he wants. They say that this is the plan after the olympics. There is rumor that Dynamo Moscow (a team which Ovechkin has considerable sway with) is going to buy out his contract so he can leave and join the caps.
Also with Traktor, Nichushkin had a one year opt-out clause for this season and exercised it to go play with Dallas instead of doing a second year in the KHL.
A lot of the higher profile Russian players have opt-out clauses in their contracts, some more complicated than others, but the reality is if they wanted to come play in the NHL they could. A mid to low level guy like Kitsyn or Prokhorkin A) may not have one or B) may not feel like they will get playing time worth leaving the comfort of their home country. Most of these opt-outs benefit the KHL teams, like you have to pay extra on the buyout or something. They make it worth their while if you want to take one of their high profiles young players, which is why you see a lot of them just finish up their contracts and come over when that happens. Unless someone is really killing it, ala Kuznetsov, you won't see the team who owns them go to great lengths to pull them over.
Obviously a lot of moving parts CAN BE involved with these things, but to state that it only happens if you "suck ass" is completely incorrect. Kuznetsov has been one of the best players in Russia for the past two seasons, and Nichushkin will be in the running for the Calder.
