Posted this in another place, got some good discussion going about it:
Limiting travel costs (eg, having unbalanced fixtures against teams in other conferences) is an important aspect, but the problem with all the "this would be a good spot for a team" is that essentially it boils down to one thing - a millionaire willing to risk $5-10m in each location willing to get it off the ground.
Finanically, you're looking at about US$2.5-$3m to run a fully pro team, while regionally-aligned mostly-semi-pro setup is still likely to have operating costs in the $1m/yr range per team. If you don't have people willing to take a hit while it gets started you end up in situations like NASL/USL-PRO where it becomes a revolving door of teams who pop up, go for a short while and go under, which doesn't work out well when it comes to sponsorships, TV deals etc.
The costs make a 12 team launch very optimistic.
The other aspect is venues; not just in terms of "this is a nice stadium in a good location", but also from a contractual point of view - not having ownership of venues means you end up missing out on lots of secondary income sources (parking, food, renting it out for other events, etc.).
You also have a bit of Canada bias, there; a 50/50 split looks unrealistic to me. The point of covering both the US and Canada for the expanded media deals is a good one, though.
I'd be inclined as a hypothetical to say 10 team league, east/west split, unbalanced 3/1 fixtures to keep travel costs down, majority US teams, some deals handled centrally (TV, kits) in order to balance out the income a bit but again it all depends on where the money comes from. Venues would need to be around the 10-15k area; enough for growth and to look Serious Business, but not enough to drown out the crowds. Maybe in some locations the smaller of the MLS stadiums would also do, but if you've got 5000 in a 30,000 capacity venue it looks rubbish.
Let's say,
East: New England (I don't have the local knowledge to say where exactly), NY, Toronto, Philadelphia, Chicago
West: Vancouver, Seattle, SF/Bay, SoCal (probably LA, maybe SD?), Sacremento or Denver.

With TSN needing to fill a whole lot of television with the loss of the NHL it would be cool to see them help finance a league like the one suggested.
Yeah, it would be cool to see, but why would they? What do you bring to the table that other hockey leagues, for instance, don't? Minority sports can often generate pretty weak viewing numbers that can be matched by cheap filler content. If you don't get a certain amount of money for it you'd be better setting up an online streaming service and charging for that in terms of direct income. There's something to be said for taking the less well paid option and building your visibility, but that doesn't pay short term bills.
