What do you think that'll happen in One Piece from now on? *spoilers*?

I mean Whitebeard is dead and blackbeard has 2 df abilities... Do you think that there'll be an arc where Luffy will fight blackbeard and actually kill him instead of just defeating him? Will the be an other huge fight between the marines and the pirates but now involving Blackbeard? I personally hope/think they'll kill blackbeard/let him die since there've been 2 character deaths of 2 really important characters (Whitebeard and Gol. D. Rogers son, Ace) and it would be bllshit if they let him live in my opinion... Soooo, what do you think? (no manga spoilers please, just what you think/what you would like to see happening) And how do you think or would like to see One Piece will end? :)
