Re: [JP] Kokoro Connect
Yaaaay, they're finally listed. And, uh, well. That's interesting. .... Holy crap, it really does look like they're doing 17 episodes.
In addition to web episodes and BD-only episodes, there's a third possibility: they actually run on TV. Remember, there have been several shows in recent seasons that were only about 6 episodes, give or take a few. I was not too fond of that being a normal option for making shows, when 1 cour (and sequels being a rarity) is short enough already. But there's a big upside: A show being able to run about 1.5 cour, instead of being stuck with 1 or going all the way up to 2 (and the production committee choosing 1 most of the time), and Kokoro Connect could be doing that.
