I believe Hall will be back in the Juniors, and Segiun will be playing for the Bruins. Nino Niederreiter and Cam Fowler will also be playing in the NHL, or maybe even the AHL. The others listen I think will be on their Junior team.
Straight from the article, "In Edmonton, GM Steve Tambellini and coach Tom Renney have been unequivocal in saying that despite Hall's perceived struggles -- the rookie left wing has just 1 assist and a minus-2 rating in five games and has been shifted to the third line -- he will be with the team all season."
