Do they have a better and bigger arena in Quebec City now or would they still be stuck in the old Colisee? If it's the latter and there's no plans to build a new one then there's no way in hell QC'll get another NHL team.
I'd love it myself if a team went back to Quebec. The Habs/Nords rivalry during the '80's was the next best thing to the Flames/Oilers hatred. Some of the best hockey I ever watched was courtesy of the Quebecers beating the hell out of each other.
Strangely enough, the best fist-fight I ever saw in my life happened back in 1984 between a Habs fan and a Nords fan. That this occurred in a Calgary high school where it was usually all-things-Flames was quite the existential mind-fuck as you might well imagine.
