Man should be a good year. Some big games I want to see.
1. Fire Emblem
2. Pokémon
3. Metroid Prime 3
4. Super Smash Bros
Those are the big four 1st parties I want to see. Then show me other stuff like the Tales of Game that Bandai has teased since launch, Bayonetta 3 and Shin Megami Tensei in action finally.
If it does the above the conference will be amazing to me. Any game surprises or new games like Animal Crossing or Pikman are cool, but not needed imo. Can just be more info on upcoming games like Octopath (which I will get, just we have enough info already), indies, Yoshi, and so on. Doesn't really matter beyond the above stuff I listed.
