About Persona, someone pointed something out.
There were photos on Twitter showing the announcements a few moments before they happened on stream. So the stream was a bit late compared to the people on the street, that's when the old woman was talking (supposedly she was actually talking about people watching the announcements on the screens and she blocked them out of sight).
Except the Persona 5 teaser.
And THEN, when the informations leak out to the web, they start the last countdown, that ends with the P5 announcement - this time simultaneously, screens and stream.
