Metroid Prime 4 with Unreal Engine 4, made by a team as talented as Retro, supervised by them, with online multiplayer as a bonus. That's it.

Now the realistic game I want to see? Zelda U/X... I know it will happen, but I really want a real trailer with some story, diverse gameplay and places.

Realistically, Borderlands 3. Might be a little early for it, though.

Unrealistically, a new Final Fantasy Tactics.

There was a time I would have said Suikoden but I don't think I want it anymore. I have no faith in Konami. I used to want more Valkyria Chronicles, too, but the game being made now is something different.

Prince of Persia open world

Kid Icarus: Uprising 2 for NX. A game like Kid Icarus Uprising but in HD would be glorious, pls Sakurai

Wanting to see a bit more on Deus Ex: Mankind Divided.

Mario game in the style of Mario 64
or
Pokemon Stadium 3

Uh oh the official game.

Actually I want a toss up of a new Metroid or Resident Evil 7.

If I had to choose, Sonic Adventure 3. At Sony's booth. Just to see them keep up with last year's E3.

Golden Sun 4 for 3DS pleeeeeaaaaaaaaase T-T

Metroid. Please.
