Aaltonen is finish not Russian, so he wouldn't be playing @ home, and Soshnikov had an out clause in his contract that forced the Leafs to recall him by a certain date or he could terminate his NHL deal and return to the KHL.
Swedes, Fins etc would likely prefer the NHL/NA to KHL given the choice. Is Russian born players and playing in their own country where these comes into play as Russian born players are given $$$ incentives with tax free earnings and bribed with bigger contracts to remain in the KHL. This is why is referred to the "Russian factor" when it comes to risks involved in drafting Russian born players.
So we will have to see with Korshkov but I would not be surprised if his next contract is one in the KHL and not NHL/AHL.. I will need to see it to believe it in this particularly case.
Jokerit don't play in Finland?
