I agree, let's hope he has an attitude that is willing to work hard for the long haul. The reports that he seemed to be sulking back in Jr. are troublesome. He only really put up a good stretch of 5-6 games in NHL pre season, if the kid thinks anything other than that he needs to work his tail off to make the best league in the world then he doesn't have a chance.
I think it's unlikely he was sulking over it, but if it's true that'd be very worrysome. He did have some great preseason games, but had a more difficult time in the last one when the game got more intensive. It was the other way around with Jesse, who played well in his last game, so I think the team took a chance by keeping him up for so long.
If his skills are even remotely as good as some say he should be able to make the Oilers in 1-2 years. I'm not really worried about that. But I have to say that based on what I saw in the WJC I think he's got a long way to become a kind of a player many thought he'd be. He looked nothing like Puljujarvi (or Laine) did a year younger or even Aho at the same age as him. Then again, Dubois didn't really shine last year and he's doing so much better now so it's still early.
