I don't think there will be a clear winner. I think there will be a lot of announcements, but nothing particularly exciting for this year. Everything will be about next year. So I will keep my expectations low.
1. Zelda Wii U gameplay footage, but won't come out this year
2. Hyrule Warriors will get a release date (this fall)
3. The Order: 1886 will get a release date (this fall)
4. Vita and memory cards will get a price drop
5. 3DS XL will get a slim update
