Hockey Canada: Announced Islander prospects Travis Hamonic & Jared Spurgron were both released from team Canada as the roster was trimmed to twenty two for the WJC.

NYI Fan Central Comments:
That leaves Blake Kessel for team USA, Jyri Niemi (Finland) and David Ullström (Sweden) so far among the Islander prospects heading to Ottawa.

Kirill Petrov is on Russia's early list for the games here but to date has not returned to play with Ak Bars from his injury to the best of my knowledge.

I will keep checking for new roster releases from other countries. Elite Prospects
here seems to have most rosters updated with the exceptions of Germany, Kazakhstan and Latvia.
