For everyone who is so fervently convinced of Ness' fate one way or the other:
Sakurai's statement does not confirm anything. The literal meaning in the english language, is that Ness is NOT in Brawl. (Think about breakfast at McDonalds--you can order a hashbrown at 9:59:59 am, but its french fries at 10:00:00am. And so in this sense, you can get breakfast up until 10am just like Ness appeared up until Brawl). However, as anyone who has studied a foreign language (and anyone who has read the translations above) knows, a translation is never perfect. So it is possible that Sakurai's attempt at being sneaky and ambiguous on Ness' fate in Japanese came off being optimistic in some languages and pessimistic in others. One way or another, we are not going to know Ness' fate until direct evidence is presented or until Brawl is out. Analogies based on other characters, prior roster history, and personal biases cannot determine anything either. Look at it this way though--Sakurai has done a fantastic job with what we have seen of Brawl so far. If Sakurai chose to removed Ness, he clearly felt that he could improve the series in some other fashion. He will not disappoint you.
That being said, suppose that Ness is in the series. Has anyone thought about the impact?? Lucas would be the first confirmed "clone" in Brawl! This would also mean that clones in Brawl are not just modified versions of other characters, but that they will also have significantly different personalities and movesets (certainly what Sakurai intended to do with Melee). So what else could this mean? Dr. Mario's return, Ike's new status as a "clone" next to a returning Marth and/or Roy, Cell Link's chances improve, and Melee clones receiveing new or similarly modified movesets. What do you guys think?
