DRAGON 2 can earn between $700MM WW to $800M. No doubt.
But I think fans of this movie wants it to do $1B WW. The original is really, uhhh, original. Very fresh, exciting kind of animation that H'wood should invest in more. Fox, with APES sequel, XMEN & MUSEUM plus EXODUS, and MAZE RUNNER & SECRET SERVICE could score good mid-range numbers, should do quite well this year.
