Beautiful stadium. I read they're planning to have 35,000 seats. The last thing you want is a beautiful stadium with 1/3 empty seats. This is a huge risk, taking into account the terrible sports scene in Florida. I hope it works out, but seating should be cut down 10-15k. Just because there is a new flashy stadium doesn't mean there will be attraction (See the Miami Marlins). Not sure if this means anything, but I've heard football songs break out at Miami Heat games, so the market is most likely there as long as there's success.
For the next market the league is interested in, why not relocate Chivas instead of expanding. St. Louis seems like the ideal location, considering the turnouts they have for club friendlies. Very large European population there as well.
