Responding to the eternal question, "Where are the 3rd party exclusives?", Nintendo president Satoru Iwata formally announced Sonic: Lost World. News of Lost World found its way onto the net yesterday, when Sega trademarked the title in Europe. Nothing else was known about it though.
We still don't know much. Iwata stayed tight lipped on the new Sonic game. Well, other than that it would be exclusive to Wii U and 3DS. The news broke on what seemed to be a screenshot from the forthcoming game, which looked very similar to Mario Galaxy, a zoomed out spherical planetoid.
That's all the news we have for now. Here's hoping Sega can break the dreaded Sonic cycle!
