Website Kikizo Games recently conducted an interview with some folks at Sega of Japan R&D, talking about everything from who influences their work, to Virtual-On and the Crazy Taxi movie.
Of the real reason you're reading this is because of Skies of Arcadia. Noriyoshi Oba commented that the game is "in the planning stages." Sure, that's all there is to go on for now, but you didn't think Skies of Arcadia was updated and rereleased on GameCube as Skies of Arcadia Legends for nothing, did you? Perhaps it was part of a plan to give gamers another chance at playing it before introducing a sequel. Or perhaps I'm grasping at straws, but you never know.
RPGFan will be sure to keep you updated on the game when new information is available.
