I'm against new domains, in fact I think we need to remove all existing country TLD's and make some contenental TLD.  I mean common, theres like 50 ccTLD for countries inn Africa, how many domains total are registered for all ccTLD for african countried combined.  I'll stake my life on less then a million, common, is it really worth it.  
www.yahoo.af (africa) is better then having 50 yahoo's for 50 countries. IMHO
