Going to watch through it now, but what I gather from comments of the stream is that:
- Ken was shown playable via CPU character, most likely voiced by Mona Marshall
- More Rise gameplay, including unblockable grab rhythm game super + underwhelming IK. Also had a bit of her theme.
- Newest P4 character won't be part of the E3 build
- There is potentially a rematch option that may or may not be exclusive to the E3 demo
-
All of the voice acting for the game has been completed
-
That P3 character deconfirmed (or are they really?)
- Final character select screen as predicted from the one in the Famitsu scan.
- Showed
English movesets for Rise, Yukari and Junpei
Also, apparently Fitzgerald was in the chat saying she's working on PQ.
