I mean, Greenwich is barely part of CT. That said, the Seattle bid is not strong right now, because they don't have an arena plan ready to go. Vegas and Quebec are the clear leaders right now. Seattle would come into play if they decide to go the route of moving the Coyotes to LV and still wanting that second expansion team out west. Their problem still remains the arena issue. So, I strongly disagree with them being the second "ranked" expansion candidate as of now.
The prospect of a second team in Toronto is ridiculous. That'd be like adding a second baseball team in the Bronx or in Boston. I know they want to move them to Hamilton, but it's just a dumb idea. The NHL gains little from it as it won't increase TV revenue, the Toronto TV ratings for the NHL are already through the roof, better to bring the league back to another hockey-starved city like Quebec.
As for Hartford, I'm not sure any investor will take the city seriously until it puts plans on paper for the new XL Center that is actually an NHL-caliber facility, and puts shovels into the ground. Until then, it's a pipe dream. The upside for the prospect of the league coming back is the Whaler brand is incredibly strong, leaps and bounds more so than when they actually existed. For a period of time recently, the Whalers were the fifth-ranked team in the NHL in merchandise sales.
