I agree with everything but the leak happened after SDCC and referencing the above video they said we have pax coming up and also tokyo game show where we will be doing character announcemens at both of those events. So they must have changed their mind, for whatever reason. Just hopefully we will get something soon.
That's not the actual quote, though. They said they'd be doing reveals at future events, but never once mention that they'll do a reveal at either event specifically. There was never one confirmation from SuperBot or Sony that they'd do a character reveal at TGS. PG mentioned that we'd be surprised, but that's the closest it's ever come to a confirmation.
Notice how he starts mumbling at that exact moment that you mentioned. That can be taken as "we'll definitely be doing character announcements at both shows," "we'll definitely be doing character announcements at all shows," or "we'll definitely be doing character announcements in the future," or "we'll definitely be doing character announcements at at least one of those." I hear the last two, personally.
