So a friend of mine sent me this link: https://github.com/djsoftware/pallan This appears to be the source for Gameloft's 'Sonic Unleashed' for mobile. This game obviously went through a few versions with different phones, but this seems to be a bit of a middle ground of the game in development. It's got a lot of tools inside it used to make the game, which might be very useful for Gameloft stuff in general. It also is full of sprite sheets of the game. Including some Sonic sprites which appear to be in-between getting uprezzed for a higher resolution version of the game. Based on this I don't think it's the source of the final version, but man, this is kind of great. Someone look to port this to Unity? :P Edit: Backup of source.
