According to a Famitsue report (by way of The Verge) Sony has halted shipments of its ultra popular PlayStation 2 game console in Japan. The last generation console has sold over 150 million units worldwide since its launch in Japan on March 4th, 2000 and is the most popular home console of all time.
The system is still quite popular despite being over a decade old, and was still seeing the occasional new game release in Japan. While it remains unknown if Sony plans to halt sales of the console in other regions, it's likely that the company will inevitably turn the page on the system to focus on the PS Vita, PS3 and its next-generation console system.
