There was a bit of commotion a couple of weeks back as Ubisoft announced the delay of Rayman Legends on Wii U in order to release it alongside PS3 and Xbox 360 version in September. Something that according to reports angered the team headed by Rayman creator Michel Ancel in Montpellier.
French site GameKult now reports (via NintendoLife) that Ancel and a bunch of leading members of the team are considering leaving the studio once Rayman Legends has been released. This as they want more creative freedom. The report on GameKult was refuted by Ubisoft representatives so it remains to be seen whether there's fire to go along with the smoke.
