Are Seattle and Quebec confirmed to be coming soon?
No. Seattle doesn't have an arena yet. Not sure about Quebec. Either way there's nothing confirmed by a longshot.
You can watch the Quebec construction in real time.

As for who to protect:
Zemgus, Ennis, Grigorenko, Moulson, Flynn
Myers, Gorges, Risto, Zadorov
Risto and Zadorov are both ineligable as 1st and 2nd year pros.
That being said, the Sabres don't have much worth protecting, so it should be pretty easy to cover all of our bases. It's the teams that are much deeper that should be worried.
They will be eligible; along with Armia, Pysyk and McCabe.
