industrygamers.com recently interviewed Ubisoft's Laurent Detoc. There wasn't much new info in the interview, but an interesting thing to note is that Detoc said Beyond Good & Evil 2 (despite its announcement and trailer at E3) may not be released, claiming "I didn’t say there’s definitely going to be another game".

IG: Most publishers make decisions based on sales, so what made Ubisoft decide to pursue Beyond Good and Evil again?
LD: “I didn’t say there’s definitely going to be another game [in the Beyond Good & Evil series]. I said something had leaked, which means we’ve been working on some Beyond Good and Evil stuff, but whether there’s going to be another game or not, that’s something for the future. But getting to your question as to why there’s work on the IP again, it’s a creative people business; the creative talent is interested in it and possibly exploring how to do it from a new angle.”
