Maybe a line or two would cover it since Wikipedia isn't a Crystal Ball, it can't predict possible future events or expansions. NBC http://nbcsports.msnbc.com/id/15420361/ says that the probability of expansion are low citing lack of arenas and insufficient profits. This article is pretty interesting http://sportsillustrated.cnn.com/2008/writers/ian_thomsen/02/13/international.expansion/index.html, however at this point it seems more like fantasy talk than any concrete plans. see also http://sports.espn.go.com/nba/news/story?id=2614550
