All jokes aside, I have a plausible theory as to who will make him bleed.
Firstly, we must understand why Norty has done what he has done.
As of now, we know nothing about Xehanort pre-BBS other than info from the trailers and reports and stuff. What this means is that we can't tell for sure what made Xehanort want to oppose the light. However, the answer is not of relevance in this theory. Why? Because Nort is still going to do what he was gearing up to do and that is take on the 7 Guardians of Light, The answer will just answer questions about why he did it, not stop him from doing it.
Now, who is going to "extinguish his light"?
I believe that it is not going to be the main cast of the Kingdom Hearts series. This is because the one who has enough courage to kill Xehanort will most likely succumb to the darkness from guilt and stuff and Terra and Riku already learned from this mistake.
My theory?
At the end of the final battle, the new enemy for the next saga pops in (of course he shall have several cameos through the game before) and takes Xehanort out like Vanitas "took Aqua out" in BBS. This action will not be of much effect as far as succumbing to the darkness goes as the new dude must already have a heart of "pure darkness". He then disappears into the darkness.
A shocker for us but not for Sora.
That is because he doesn't exactly know what side the "enemy" is on. Since he doesn't know him/her,he won't acknowledge much and BAM!. Happy ending. At the start of the next game, maybe we can have Sora start another journey from Destiny Islands/ new home world to go after this new enemy
