Ultimately, maybe helped along by some desperate and crazy NPCs, N'Zoth is spared destruction and his bindings are broken, unleashing the full might of the Old God against the Legion. We've fought the Old Gods many times over the years, so this would be the first time we'd actually get to fight alongside them. Both sides would be fully aware that as soon as the Legion is dealt with, they'll be back to trying to kill each other. But N'Zoth's release would set him up to be a major threat in a follow-up expansion, maybe one dealing with Azshara or Azeroth's underworld.
