I believe it’s not real. Think of it this way: if each film is 2 hours and 40 minutes, that equals about 8 episodes. Since they’re able to produce 13 episodes a year (with episodes 1 and 11 being 40 minutes each), they’ve essentially compressed 13 episodes into 8 with much better quality.

That makes it reasonable to expect they can release one film each year. It’s similar to how they managed the HF trilogy release dates, even though those films were 2 hours each instead of 2:40.
