I do want an nhl team back sure, but at the same a small part of me doesn't... i'll explain;
Since the Jets left, i'd have to say the appeal of the blue bombers hit an all time high - maybe if we won a cup or 2 like in the 80's, it'd be an even crazier amount of support. but i'd say generally, it's been good having the spotlight on the blue crew and hope it continues.
When i look at other cities with big league teams, like the flames, canucks, leafs, habs, (i'd say oilers too but the eskies made themselves pretty respectable in edmonton), i dont see the enthusaism like the riders and hamilton (well till they started to stink over the last half a decade) and winnipeg, since the jets left. I dont know how much that would hinder things in terms of support, but a new team would for sure steal all wind the bombers have been building at least for the next 5 years till a new nhl team would be come the norm again like the jets were.
I do think people will still go to bomber games as they play in different seasons, however it could dent season ticket sales and general interest as everyone would want the 411 on a new nhl team such as who are we getting for players and who CAN we get via trades/signings as we'd basically have to start from stratch or take of a team that obviously wasn't doing it right to have been shown the door of their respective city.
