"Unfounded rumours!" Ubisoft France spokesperson Pascal Lecointe told Eurogamer France on our behalf. "Michel is currently working on Rayman Legends, a unique game that will be released on Wii U, Xbox 360 and PS3.
"Michel Ancel and Ubisoft therefore categorically deny these rumours."
A Ubisoft UK spokesperson refused to deny the suggestion that Ancel was leaving, simply telling Eurogamer that the company "would not comment on speculation and rumours".
I have no idea what Gamekult's rumour record is, but here.
Long and short of it, they're claiming their source states Michel Ancel, along with five/six people, are humouring the prospect of leaving Ubisoft once all of Rayman Legends is complete. The reason being the desire to detach from a large company and find more freedom in creation and organisation.
According to them, Ubisoft is aware of Ancel's position. Ubisoft has "categorically denied" the report, apparently.
"Two delays and the loss of temporary exclusivity for Rayman Legends on Wii U might have pissed off players, but it's also causing quite a stir at Ubisoft Montpellier.
Based on several sources, Michel Ancel might be thinking of leaving Ubisoft with his own team once Legends is finished, and start a new project with other people (different company?). He talks about wanting more liberty in creating and organizing his project. This is not the first time Ancel has spoken of leaving, but so far he's always stayed with Ubi.
Development of Rayman Legends is pretty much over, even though there is some work left to do on the PS3 and X360 versions. Ancel would like to calmly leave Ubisoft, taking some people with him. If it should happen, it wouldn't be a crying affair. Ubi is aware, and they might choose to be involved in Ancel's next project either way, even if he chooses to leave, as per an anonymous developer. Another source says Ancel has already given notice he is leaving, as he has other contacts and projects he'd like to work on. Five or six Montpellier personnel would be ready to leave with him. The idea is that Ancel would remain "tied to Rayman", whatever happens.
This might explain in part the further delay and the premature announcement of the Rayman Legends port to other platform. With Ancel possibly on his way out, he would have less motivation to contest the decision to port, as he is already looking to greener pastures. Several sources state Ubi and Nintendo were unable to come to an agreement on distribution and marketing of Legends, which was a reason for the port to PS3 / X360.
Ubisoft and Ancel categorically deny these rumours. We probably won't know much more until a couple more months, unless more sources start spilling the beans."
Like I said guys, just a quick translation.
