The only reason Guillermo del Toro's "Pacific Rim" would warrant a sequel is because of its popularity overseas.
China is currently the largest source of international box office earnings, and by 2018, it's predicted to be the number one source for box-office income. Thus it's no surprise that "Iron man 3" had alternate scenes for Chinese audiences and upcoming sequel "Transformers: Age of Extinction" was filmed in China.
