In a speech given today at CinemaCon, the exhibition industry’s annual convention in Las Vegas, James Cameron has announced he’ll make Avatar 2 and 3 “with a native frame rate of 48 or 64,” which will deliver fluid motion in the vein of Maxivsion (which Roger Ebert has been promoting for years) or Showscan. Cameron will demonstrate various frame-rate samples tomorrow at the Coliseum theater inside Ceasar’s Palace.

MSN’s James Rocchi tweeted as follows: “James Cameron keeps talking about Avatar 2/3. It’s the only time in history the nerd who wants a sequel nobody else does has the power to do so.”
