One of two things will happen from this:
1) Disney will not have learned any lessons from the past on how they soured many of their franchises, and start spamming everything from Frozen to death and back.
2) Or they'll realize that Frozen, while an "Ok" film, was not THAT great and really only exploded the way it did because the internet turned it into a meme. They'll also realize that Frozen's success, despite being a demonstration of the undeniable power of the internet, is also a strong indication that people love and miss Disney's old approach to big-deal, animated musicals. And hopefully, they'll make more of them...unrelated to Frozen. Please god, no more Frozen.
It'll be interesting to see which way they go with this.
