ESPN reports that there is a group that wants to move the Expos to San Juan, Puerto Rico. As I indicated in my Expos relocation study, Les Exits, San Juan is the largest metropolitan area in the U.S. or Canada without a major-league team (slightly larger than Portland, though it has about a million people fewer than Montreal).
Although Puerto Rico has supported a winter league and a series last year to open the major-league season, it has not had a team in organized ball since the one-year Inter-American League in 1979. The stadium only holds 20,000 people. Its businesses and population are not thought to be extremely affluent. I would doubt that they could get a great cable deal. All of this adds up to a big goose huevo for San Juan, but it is an interesting idea. Maybe proving themselves with a minor-league team that is successful for 5-10 years would help.
