I can't say I disagree with those saying they should leave it at a trilogy. SA2 is a super climactic story, so a good place to leave it off. Nice and clean. I feel like that's not gonna happen, though. LOL Let me put my wild guess in so I'm a genius if I get it right: Movie 3 is gonna end with Silver seeing the world broken apart with purple Dark Gaia energy everywhere and he's going to be seeing visions of the Warehog destroying the planet. That's right. Movie 4 is 06 + Unleashed. The Flames of Disaster is replaced with Dark Gaia and there's no Soleanna or Elise, Sonic is racing around the world turning into a warewolf, and Silver is chasing him trying to save the future. Professor Pickle is there, too. Chip is a "maybe".
