Making predictions is always difficult, especially about the future. But my prediction would be a new game mode, especially something that requires clan cooperation or similar, rather than this.
I think it would be harder to call a clan war tournament bigger than war itself. Also I think I recall someone posting a quote of one of the mods/youtubers rowing back on the hype just a little and saying that "some players will prefer war still" - as if it's an alternative, not an extension
I also think a clan war tournament by SC would require some drastic conceptual changes to the game. CWL works because all the clans buy/recruit accounts upgraded to the limit of the allowed b/d. Events like the forum cup no-dip worked because the organisers could assemble the clans so they matched (and just leave out all the engineered etc accounts that didn't match well). A tournament for existing clans has serious problems with matching, that will make the current MM look like perfection.
