www.sonicteam.com has just been updated, with an all new PSO Website deticated to it! This new site includes actual art of Characters seen in the game, to the actual storyline!

Unfortunately, the Site is only in Japanese. As the English Site is still under construction (Hopefully they're converting all the pages just for us poor english speakers), But if you happen to know where to get a decent Japanese translator, then go wild, and tell the world what the jumbled mess says at the Sonic HQ Mobius Forum

Also in the Sonic team Update, The Yuji Naka Picture page was updated again. This time with pictures inside their Studio and various other places. Noticably a Train with this plastered everywhere:

O_o.
