Well for those who can't wait, I've uploaded screenshots of the stream
here.
Seeing the new seiyuu's being nervous was quite amusing. Yuutaro Motoshiro (15 years) was the most nervouss of the trio. Kanako Miyamoto (22 years) sounded a bit like Rie Kugimiya to me. I liked her enthusiasm. Not much to say about Ayaka Ohashi (17 years) yet. Chiaki Omigawa sounds nothing like her usual roles at all, which surprised me a little.
The episode recordings start next week but Miyamoto says that the first episode does feel like a sequel to the first series. Boy are they really having a ball with the use of "aratanaru". They definitely named Naru like that just so they could whip all those lines out.
