Fans are already ready for that inevitable "Avatar" sequel. But will they still be ready in three years?

After James Cameron's 2009 "Avatar" grossed more than $2.7 billion worldwide, news of a sequel -- with a tentative release date of 2014  -- started to grow. Now, we're hearing otherwise. Producer John Landau told Empire, "We're not naming dates, but I think 2014 will be a tough date for us to make. It's about getting it right." 

So, that means that part 2 won't hit screens until 2015, with a third one likely to follow a year or two later, giving writer-director Cameron and his massive FX crew plenty of time to gets things right. "Movies make release dates; release dates don't make movies," Landau added.

Earlier reports indicated that the famously ocean-obsessed Cameron will explore Pandora's seas in the sequel. "It's going to be like the Floating Mountains in the first movie," Landau elaborated. "It's not going to be all underwater; it's going to be a place we go to, leave and come back to."

Meanwhile, James Cameron's other billion dollar epic, "Titanic," is back in theaters, in 3D.
