Really, I don't see why an official announcement would be necessary to convey that he's dead. As I said earlier in this Thread, writers tend to use the story itself to convey their intent for a story.

Well said and i shall use the same evidence but first just let me say...between Aeris's death and vivi's there is quite a diffrence..now i realize i may seem to be straying off track but work with me here...when aeirs died...she died..we all knew it....you cant deny it..cause not only was it right there in front of your face but it also protained to the story...vivi's death...is a bit of a diffrent story...now as you stated quite wisely that we may not have seen his so called "demise" or "stopping" but we can use evidential proof from the game itself correct? Now with that i believe that it cant be stated full heartly regardless of this notion....vivi contemplated his death...sorrow..throughout the entire game...as stated through out this entire thread...we all know this... :rolleyes2 now from this we can assume one of two things at the end of the game...that one through his journy with his friends and zidane vivi was able to conquer death even though it was his destiny from the begining...his ability to be diffrent from the other black mages allowed him to gain the strength to live...OR...we can say that because of his sorrow and his journy with his friends..he was able to accept his fate and gain the courage to face the one thing he ultimatly feared....now this may not be REASONABLE evidence...but it works for me (as i said i am a vivi fan) so..take this as you will and your welcome for the tissue
