I speak a little bit of French. Just enough, in fact, to get the gist of what Rayman creator Michel Ancel is saying in this interview. The Ubisoft developer confirms work continues on the long-awaited sequel to cult favourite Beyond Good & Evil, but also says that it'll need better tech than is currently available.
I'm paraphrasing here but Ancel basically says that the game is indeed being created he can't say when it's coming or for which platforms. He also says that the game needs-either better or more -- technology to succeed and, when asked if Mirror's Edge was an influence on BGE2, that the work seen in the trailer was completed before he was aware of the EA first-person-platformer.
Ancel elaborates that BGE2 will have a very dynamic camera system which will make it seem as if the action is being filmed live. This detail fits with BGE heroine Jade's role as a journalist. But, this is apparently one of the areas where the increased power of future consoles is needed. So, we'll have to wait for a while longer until we can revisit the planet of Hillys.
