Hmm I doubt that. It already met the requirement of broadcast syndication at 65. A second 65 isn't going to unlock them anything.
Edit: Take
this list for example, the only show on the list that had a milestone at 2x65 episodes was He-Man. Once a show goes past 65 it just means it can end anywhere they like.
65 episodes isn't a syndication requirement, it's a package that pulls in the best price on the syndication market, because it can be conveniently scheduled.
13 episodes can air once a week for a season (usually a weekend timeslot, or filler for a bigger weekday slot that doesn't have enough episodes).
26 episodes can air once a week for two seasons, or twice a week for one season (it can air on Saturday
and Sunday).
52 episodes can air once a week for an entire year, or it can air four days a week for a season, assuming they can find a suitable 13 episode show to cover the fifth weekday.
65 episodes can run five days a week for an entire season. That's the big leagues of scheduling.
Once you get big, maybe you can throw your weight around and make people adjust their schedule around you, or maybe sometimes you get canned before you can make another 65, but it's never a bad idea to have cleanly-defined packages that make the schedulers love you. Two 65 episode packages means you can run five days a week for a solid six months.
Although I'm not entirely sure that MLP:FIM got trimmed in S3
just to make a 65 episode package. Also note, if they hadn't trimmed S3, we'd already be set to have two 65 episode packages by the end of S5.
