I wrote up a quick list of players that stood out to me during the WJCs.
I watched quite a few of the games but how closely I was watching varied and I certainly don't consider myself an expert for spotting hockey talent. I certainly missed a couple Russians (their names are too long and hard for me to keep track of) and I didn't really see any of the Czech's games.
I tried to put them into a bit of a ranking order but don't look much into it.
