Funny, yet pointless. User mods, levels, custom patches, etc on UT3's scale is a new thing for consoles. Microsoft couldn't stop this if they wanted to. Once they add similar features to 360 games, sure we can expect Mario, Metroid, Snake, Killzone, etc user mods for 360 games.
I don't think Sony would want a console like the PS3 to be too much connected to a specific mascot.
