E3 is more of SONY and Microsoft, but this year it seems Microsoft need to prove more and succeed more on E3. Nintendo seems had been left E3 and their targeted market are not on E3. I believe SONY are not fully ditching E3, this year a bit different because they are satisfied with their sales and trying to focus on their first party games sales. We will see more classic presentation on PS5 reveal in 2020.
nintendo is at E3... they havent left. Just because their presentation is different doesnt change that.
and we are getting a classic presentation from Sony. all they have done different this year is tell us which games they are going to highlight.
