Has the Russian roster(s) been released somewhere?
Nope, just, if I understood correctly, the QMJHL announced their players to play for Team Russia.
Although I'm seriously souring on Lipanov, if WJC was today, Bragin's team probably resembles the following locks.
X - Shen - Kravtsov
X - Lipanov - Kostin
X - Anokhovsky - Kovalenko
X - X - X
Alexeyev - Samorukov
Morozov - X
X - X
X - X
Tarasov

Well, more or less your version is the same as mine, although I'd say Maksimov and Chekhovich are very strong candidates as well. Maksimov is basically the only right-handed sniper candidate (ok, there are also Morozov and Denisenko, but they are 2000 borns, so Bragin will take them only if they're too good), which is critical for the PP. And Chekhovich, as I've already mentioned couple of times here, just because he has been very good. Also about goalies, it's hard for me to imagine that, if WJC would start today, Ustimenko wouldn't be there.
