The PlayStation 2 launched in Japan on March 4, 2000 and the console lived beyond its ten year expected life cycle. Sony continues to ship new PS2s, but they won’t release any more new consoles in Japan.
After this batch of PS2s you’ll either have to pick up a used console or scour Yahoo! Auctions for a new one. New PS2 games still get made like the Final Fantasy XI: Seekers of Adoulin expansion disc, which will be available in March 2013.
Over 150,000,000 PS2s have been sold worldwide and Sony will continue to ship PS2s in other regions. The system just launched in Brazil back in 2009.
