Jeremiah Slackza, that's the creative director of 5th Cell, says:
"I think a Wii version could happen. It's all about the fans - if the fans speak up and continue to buy and play the second one like they did the first one, I don't see why we couldn't make a case for a Wii version."
"Fans need to show WBIE(Warner Bros.) they want more of the franchise, and then we can see where it goes!"
And the possibility is very real. Sounds like 5th Cell are enthusiastic about bringing the series to Wii if it takes off again on DS. A great success story. Iron out those flaws, and the game is perfect.
