The dropdown list is far from conclusive imho, since it contains every generalized area in the area. While that's a starting place it does not tell us whether, for example, the donovan is considered part of downtown. There's also the question of when they'll start offering the service - they could be lining up salespeople a year in advance.
I was hoping to make it to the session myself just to see what I could find out, but I won't be able to. =\
