Yep, SoA is rumored to come to PSN/XBLA and Vyse is confirmed to be playable in Sonic & Allstars Racing Transformed.
I wonder if good sales of SoA and Shenmue on PSN/XBLA could lead to sequels. I remember the sales of Sin & Punishment on the Wii VC convinced Nintendo to fund the (excellent) Wii sequel Sin & Punishment Star Successor.
I really don't see how this game could have a sequel, it ended so nicely. What would be great is if they made a prequel. I'm not saying this out of love for the trend (of prequels) but because there would be more material to work with if timed in the ancient world. Plus, we'd get new characters as well as whole new cities and scenery.
Yea I agree, I don't think a sequel would be necessary, maybe more a game chronicling the downfall of the ancient Skies werld when people started to use the power of the moonstones, to travel and to make the Gigyas and whatnot. I always wanted there to be a lot more explanation as to why the islands in the game were floating anyway and if anyone lives on the floor of the world.
