I think you're going to be disappointed.
The thing with the team is, the roster has been absolutely savaged by injuries and the Vrana situation. Yzerman could well decide to hold serve, have Berggren on the roster full-time next year, promote Edvinsson, bring over Kasper and Wallinder (who are currently 3 and 1 in U21 scoring in the SHL, respectively), and hope to snag one or two decent free agents to shore up the roster. I would rather resign Bertuzzi than trade him for a second. His injury history will tank his trade value.
The injuries throughout our roster and the loss of Vrana tanked the team's offense, and no one except Larkin has any trade value as a result. I would rather jettison Suter and Zadina, hold on to the roster, bring over Kaspar to help fill in our center weakness, bring over Wallinder for the third pair, and hope to sign one or more of O'Reilly, Tarasenko, Pastrnak, Dumba, Gostisbehere, Severson to fill out the roster and push out some of the remaining AHL garbage.
I wouldn't be surprised to see Yzerman stand pat and keep the entire roster for next year. I think he is at the stage where is looking at making small changes every summer and iteratively improving the team.
