I don't know about there not being any character development in Metroid. For me, at least, Metroid is very much about character development. It's just that the usual character development in Metroid is through the power-ups. Now these clearly aren't the same types of character development, but I think it means that they understand what makes it compelling. Just saying, I wouldn't give up on it just yet. Especially after all of the controversy surrounding Prime before it's release turned out to be nothing. I think Nintendo tends to know more about Metroid than the fans give them credit for. I'm not saying the story will be great, and I'm still cautious, but I think we have to wait and see before passing judgment.
