Playstation has more regional youtube channels than Nintendo. Adding it all up will just make it even more one sided to Playstation.
Also State of Play are tiny updates. Showcases are the big E3 like conference replacements.
PS5 thus far is the fastest selling console of all time.
If you look at the game trailer views from the recent PS Showcase they wipe the floor with Nintendo's E3 direct, despite only being 3 weeks old.
