Everyone's cancelling events due to Covid19. Sony shouldn't be singled out. And you shouldn't expect Sony to then suddenly have alternative online reveals ready. They need to scrap their old plans and come up with new ones and create their preferred online messaging. Give them time - no-one foresaw Covid19.
I don't understand the emotions attached to a lack of news. It's not like PS5 is cancelled. If you feel your life is empty without some specs and game trailers, maybe you should think about branching out into some new interests and experiences while waiting?
