Considering that it's not even the middle of the year yet, I think there's still hope for an LBT 14. I mean it took the last sequel until the near end of November to come out if I remember correctly. Maybe the same is going to be true for the next sequel.
If they do do Land Before Time 14, I hope it'll explain just who Ruby and Red Claw are, how Ruby knows Chomper and his parents and why Chomper's parents entrusted their son to her despite that Chomper's most likely stronger than she is. Oh and of course, how Chomper and his parents got off the island.
