It's already reported that Sega are working on a "next gen" edition of Sonic for Xbox 360 and PS3, but new IGN.com suggest they're working on another title exclusive for Nintendo Revolution. This, we expect, would be something to do with the unique controller Nintendo have designed.
There have been countless rumours about Sega's intentions for the upcoming Nintendo console, all of them seem pretty credible and positive. After successful partnerships on the Gamecube platform maybe Sega are enjoying working with Nintendo rather than against.
IGN have even gone one step further to suggest Shigeru Miyamoto and Yuji Naka want to do a Super Mario / Sonic crossover title. Now that is a bold idea, I'm not too sure we'll see that one though, unless the two gaming pioneers get really cozy.
