Nah, definitely it's not. The franchise is just plain extinct now (lame pun), but I wish they could make a new film that would act as the grand finale to clear LBT's name after the disaster Wisdom of Friends was, something that would be more faithful to the source material while keeping the sequels lighthearted tone. But, well, it's all over and Littlefoot's story has ended, so, yeah, this shall never happen, unless in an alternate reality
