Do we know what happens to Spike at the end of Cowboy Bebop? At the end of the last episode of Cowboy Bebop, Spike collapses.  It's not clear, but it looks as though he may be dead.  Is there a way to know whether he is alive or dead (something in the background, comments from the director, a continuation in the story in the manga, etc.)
According to Wikipedia:


  However, in an interview, Watanabe stated, “I’ve never officially said that he died. At this point, I can tell you that I’m not sure if he’s alive or dead.”
