I am excited by the prospect of a WHL team to the city. I do not follow the league at all, and this would peak my interest a bit. I would attend some games, I hear they are fun. If it's private funding, then I say go for it - would be quite interesting if Winnipeg ended up supporting NHL, AHL and WHL!
But I gotta say it - some sad Kootenay Ice fans, people hurt by this news, and I can't help but feel for them - especially as Winnipeg doesn't need the WHL.
Edit:
Re: demographics, I think it's important to add that WHL will draw from a different market too. They'll have A+ access to the Perimeter which should make it easier to draw a more rural "out of Winnipeg" crowd as well. I also do not see WHL directly taking tickets away from Jets. Completely different markets, and Winnipeg is an NHL first town for sure. WHL will certainly have it's place but it won't be enough of a draw to take away primary interest from the major league club. Especially not when it's a cup contender!
