It means less of those dumb skits they always did during the Wii U days. Honestly I prefer the old E3 way with the epic presentation and such. Anyway if one were smart and didn't want to come out disappointed they won't have high expectations for next week.
I mean they said that only 2017 games will be shown. The system launched in March. So we know MOST of the lineup. At best we could get one big surprise announcement (That's not Mario vs Rabbids. ). However even that's pushing it.
