IT would seem sort of redundent to have a sequel t oit. If you saw the scene at the end and knew that the developers of Shadow of the Colossus also did the game Eco; then you would know that the hero reborn with horns actually shows how the horned boys in Eco came to be. It may sound wierd how I worded it, I got that from somewhere, and I know nothing of the Eco game, eh.
In short, ant Eco game(s) are sort of a sequl.
And it would be lame, especially on the Wii.What I'm saying is, A Shadow of the Colossus would be great for the next gen consoles (especially the Wii).
