Samus in Marvel: Ultimate Alliance?

Marvel: Ultimate Alliance was one of the better superhero games to come along in a while. It had tons of marquee characters, a decent storyline that included most of the villains in the Marvel Universe and had 4-player online co-op. But did you know it almost had Samus Aran and Link as well? Go Nintendo has a YouTube clip (see below) of Samus roaming around in the Wii version of the game, but apparently Nintendo wanted nothing to do with it. Shame really. They'll let Link be in Soul Calibur, but not in Marvel games? What gives?
