Disney pretty much stopped DTV Cheapquels.  Tinkerbell became a DTV franchise, but that was actually based on a series of Italian Comics (no freaking Wizards of Mickey or Paperinik of course 

 ).  Frozen 
did make a crap-ton of money, but I don't see they really doing a sequel (especially one DTV).  If anything, we need a sequel to Wreck-it-Ralph, if only to clear up 
why the game's called Fix it Felix 
JR.  And for more merchandise.
 
But the 
only reason we get odd sequels to modest to barely adequate at the Box Office films like Alpha and Omega (again, they're a much more advisable target over Bronies...at least MLP:FIM is 
good) and The Nut Job is because they're made by these smaller fifth party studios who want to have a franchise over more creative means.  Seriously... the Nut Job studio 
really should consider a Bolts and Blip movie (they animated that series too) over a Nut Job sequel. 
 
Side note: I can't recommend Bolts and Blip enough.  It's surprisingly good, and the best CGI television animation I've ever seen.
