My take on it:
Sony - current console market leader, selling at a record pace. Needs to stick to games. Talk about the "big guns" - God of War, Gran Turismo, Last of Us 2. Would also like to see the mid tier games like Spider-Man, Detroit Become Human, and Ni No Kuni 2.
Nintendo - I think Nintendo needs to keep the momentum going. They've announced a bunch of games for this year already, but it would be amazing if they had some good surprise announcements similar to how Sony introduced Final Fantasy 7 remake and Shenmue III. I think it will happen.
Xbox - Scorpio will be a big deal at E3, but I really hope they announce some big exclusives for the system or I will just stick to my PC. I think the price will surprise people.
Overall, it's hard to say who will win because all three have potential to have a great e3, but, I think MS will take it because of Scorpio. Console reveals are always such a big deal at E3 and they get tons of press. So what do you think, SW? Who will win E3 2017?
