Well, there's some rumors on that. Some say he did die. Other say that he is simply in a coma, because Morgana said, and I quote, after Layla asked "Will you take care of him?", and she replied, "Until he wakes up again, you have my word." And if the second movie, Winx Club 3D: Magical Adventure, IS after Season 4, then Nabu would have already been awake, as he was in the movie. I, myself, hopes he's in Season 5.
