The first game was pitched as a cinematic experience but the PlayStation 2's Emotion Engine scuppered that idea, and so they sacrificed their dreams.
Ubisoft's Michel Ancel reveals that now the technology is here, Beyond Good and Evil 2 will be grander in size and immersion. Their goal is to make their new limits almost invisible to players.
There is no release schedule for the sequel right now and no confirmation on what platforms it will arrive on, though an appearance on next-gens and PC is expected.
With talk of technical limitations hampering the first game, it's unlikely it will see release on Nintendo Wii though Ancel wouldn't rule out a future port when speaking with. The game appears to be in pre-production at the moment so it's going to be quite some time before it arrives.
