In North America and Europe Sonic Unleashed is exploding on every viable console on the market with a PlayStation 3, Xbox 360, Wii, and PlayStation 2 version that Japan isn’t getting. Sega of Japan plans to release Sonic: World Adventure (renamed to better fit Sonic’s journey around the Earth and downplay the Werehog thing?) only on the PlayStation 3, Xbox 360, and Wii. The PlayStation 2 port will be completed before Sonic: World Adventure launches in Japan so this begs the question why is Sega passing on it? It’s not like Sega Japan is abandoning the PlayStation 2 entirely. Thunderforce VI comes out on Thursday in Japan and unless Sega has anything secretly planned it will be the final PlayStation 2 game published by Sega in the region.
