Smash Bros. Trailer, Mario Kart 8 Trailer, and "X" from Monolith Soft gameplay made it far more than I expected or hoped for. I feel like they will probably just do 1-2 more small, simple Directs before E3, likely without revealing many/any new games, and then at E3 we'll finally get a glimpse of the 2nd half of the year (X, Bayonetta, Smash Bros. included) along with plenty of new game announcements to flesh out the 2nd half AND some games that will be 2015 (like the Wii U Zelda reveal for instance).
Upcoming Games To Get
Definite: Kirby Star Allies (Switch), Mario Tennis Aces (Switch), Fire Emblem (Switch), Yoshi (Switch), Pokemon (Switch), Kingdom Hearts 3 (PS4), Monster Hunter World (PS4)
Considering: Fe (Switch), Donkey Kong Country Tropical Freeze (Switch), The World Ends With You (Switch), Ys VIII (Switch), Street Fighter V: Arcade Edition (PS4), Kingdom Hearts 2.8 Remix (PS4), The Last Guardian (PS4), Shadow of the Colossus HD (PS4), Anthem (PS4), Shenmue 3 (PS4), WiLD (PS4)
