I can't see it happening, not while the merchandising is doing so well. They make more dough from that than from the movie tickets, so why bother. GL hates making the movies anyway (and he really hates making prints and the cost and hassles of distribution). A season of the cartoon gets you close enough without the effort, the only part you miss out on is theater tickets, which gets divvied up too much anyway.(Plus, you don't have to make up a whole new phoney baloney reason the new "story" is just too important not to tell.)
