First of all, an official trailer video for Beyond Good & Evil 2 was released a while ago, so you will want to watch that first. See the SD version or the HD version on GameTrailers.
New however is this video on YouTube, supposedly containing leaked BG&E2 footage.
The video looks pre-rendered, but I wouldn't mind playing parts of BG&E2 that way. There seem to be no anthropomorphic animals or anything else alien you'd find on Hyllis. The location looks inspired by India, Earth actually. The original game never mentioned Earth or discussed humans specifically, but it's possible Earth does exist and the sequels features it. Maybe the video is just a proof of concept thing using a placeholder location and placeholder enemies. Whatever the case, the running woman looks identical to Jade in the first teaser.
