MLB Expansion and Reallignment

It has been over 10 years since MLB last expanded, yet attendance has continued to rise. Now that MLB had cleaned up its internal problems with Steroids and the Collective Barganing Aggrement, perhaps expansion is in the near future? What two cities would you like to see get MLB clubs?

Here is my proposal for reallignment, which takes a book from the NFL with 8 regional divisions.  I chose Charlotte and Portland for expansion.  Folks in the Carolinas currently have only the Braves to root for, and Portland would provide a natural rival for Seattle.
