Battle for Runeterra

So I've been thinking. When Riot came out with this new lore, they had TWO empty spots. Now in Aurelion Sol's lore, we see that something from the Void is laughing at him. After that, Aurelion Sol says he will come back, and "make an example of Runeterra". So we might have a really big battle. Going back to the guy in the Void that laughs at him, that could be a champ we already have, say Kassadin. But nobody should ever laugh at a dragon that can make stars. Only someone really powerful would do that. Also, we see that many gods are inhabiting people like Diana, Leona, and Pantheon's alter ego. So that could mean that another POWERFUL champ will come.
I hope I am right in saying this, but I think that Riot will release another champ soon, and then we will have this beautiful plot come together where all the champs (minus Taric) come together, and this would open up into another GAME that is about the story line.

Really hope I am right, probably too far fetched on it though. Please respond though, because that would be great! Got2 P.S. Jk on the Taric thing :) P.s.s i got doing this. Haha, haa.
