Yeah, it won't be against The Seven Deadly Sins. My guess it's probably one of the cliche types: they know that there will be war and start to prepare for it, and their action in reality will lead to that war. Meaning if they didn't know a war was coming, there wouldn't have been a war. And it will be probably internal conflict between the holy knights for taking over the kingdom (and the seven deadly sins may join one of the sides, or be a third party in the war).

Meliodas the traitor? Ain't all the traitor stuff come from someone apologizing to Meliodas before knocking him out? Then how will Meliodas be the traitor? The most logical option is Gowther, since his identity is the most unknown. He may have started the plot to overtake the kingdom and may be one of the main holy knights without even someone knowing he is from the seven deadly sins
