The delay of Rayman Legends for Wii U to September to coincide with its launch on PlayStation 3 and Xbox 360 may have been unpopular with fans, but the good news is that developer Ubisoft Montpellier has had time to add more new content to the game.

Ubisoft has used that time to add 30 new levels and some new boss fights, senior game manager Michael Micholic told Official Nintendo Magazine (via Joystiq). "Trust me, the things we are adding aren't minor. We're not talking about adding some polish here and there."

Rayman creator Michel Ancel said the delay of the game was hard to accept as first, given the reason. "It was really hard for us," he said. "Of course, there are more important issues and problems in the world but we worked really hard to make something and were so involved, it was difficult for us and the fans."

In response, Ubisoft has already released one demo on Wii U. A second demo is planned for later this month, and will include an exclusive Wii U level called Murfy's Dungeon.
