It was described specifically as a "Community Q&A" in the first official info I received about Friday. They used the same description on their
Eventbrite ticketing page.
I don't know what I'm going to ask because I don't know what's going to be revealed about GT Sport during the press conference. It is likely they will speak at length about the updates to sound, physics, damage, features, online stability, etc., rendering the most pressing and relevant questions here obsolete. If not, I'll ask about the topics which I feel need more attention.
Kazunori is typically the most forthcoming and enthusiastic when asked to expand on details of features he has just announced. Instead, most interviewers spend their time asking him about things which aren't ready to be revealed; he then either avoids the question or makes over-ambitious statements about features that are not fully formed.
I will certainly browse this thread to see what people are most interested in as the event unfolds, and I hope people who do have the opportunity to ask questions on Friday will use this topic as a similar source of inspiration.
