It doesn't help that Sony's first public discussion about PS5 was an hour long technical breakdown with very little for the consumer.
Maybe because this was the talk M. Cerny was supposed to give at GDC?
It has nothing to do with "a public discussion" at all. It had nothing to do with "the consumer".
You know, GDC is for people who are actually supposed to program the damn things. They more or less (yes there were a few "creative sidesteps" in his talk) got precisely what was announced.
Sony could have announced the stream with "If you are a gamerzzzzz, don't listen to it", but I'd reckon that would not have gone too well with said group.
