The only information thus far (apparently mentioned in a Reddit AMA at unknown URL):

The contract details are not quite finalized, but we wanted to clear the rights to at least get the first episode out so we wouldn’t have to delay the whole series. We try our best to provide as much information as we can regarding delays, but sometimes we are contractually bound until everything is signed and stamped.

The season 2 comes out with 13-minute episodes, which means a dramatic upgrade in storytelling capacity. But the first thing they did with it was to run a story arc for 3 new episodes.

Dear Evilest Chairman Kadokawa or whoever, please stop depriving us from the cute.
