Yup, E3 is always exciting.
Microsoft has had the best conferences the past few years imo so I'm expecting a great show again. Pokémon Sword/Shield will probably be the game that makes me buy a Switch so naturally I look forward to see Nintendo's stuff as well.
Sony's no-show is a bummer. They'll probably have a "PlayStation Meeting" at some point this year but I hope they return to E3 in 2020.
