ICANN is considering opening up the top level domains to 100's or 1,000's of new ones. Min cost probably $100K to get one of these (and then manage the TLD as your own registrar).

This could lead to a new gold-rush for this name space.

Quoted: The Internet's key oversight agency relaxed rules Thursday to permit the introduction of hundreds, perhaps thousands, of new Internet domain names to join ".com," making the first sweeping changes in the network's 25-year-old address system.
