It looks as if Sonic might have unpinned his colours from the Nintendo mast.
As confirmed last year, Sega had signed up to a three-game deal with Nintendo that included Sonic: Lost World, Mario & Sonic at the Winter Olympics and an as-of-yet unannounced title.
This could be an entirely different game, of course. But if that's the case, why isn't the Nintendo-exclusive title on the roadmap?
If true, the new is yet another big blow to Nintendo's machine which has previously lost exclusivity deals on a number of titles such as Ubisoft's Rayman Legends, Tecmo Koei's Ninja Gaiden and Square Enix's Deus Ex Human Revolution: Director's Cut.
And while GameStop has subsequently come out and claimed that its removal of listings for the Wii U version of Watch Dogs was a technical error, Ubisoft has repeatedly declined to clarify the SKU's future when asked by a number of publications.
