That's a good question.
Didn't Tabata say something like "We want to do another show like this if we have enough material"? To me it sounded like they weren't sure if they'd actually do another stream that early, but I might have misunderstood that part.

I wonder if the stream will be all about XV then, since they showed only about 10 minutes of Type-0 & Agito and then focused on XV, anyway. They might answer some more questions if there are any new, and maybe they'll show a few more seconds of further improved gameplay. I think the other guy also said something like "We're gonna let you know more about the characters and the story at a later point", but I think he was rather referring to Jump Festa. I wouldn't mind some new info during the stream though. ;)

They might also completely focus on Type-0 next time, who knows.
