It's the biggest game of Nintendo's show, and the one they've clearly stated will be the main focus of their whole presentation.
But what will they actually show of it this time?
Will it be more of the content we've already seen, like New Donk City and the desert level from the first trailer?
Is the plot going to be a big feature here, with Nintendo explaining how Bowser's 'marry Princess Peach' plan got off the ground or why Mario's flying around in a ship shaped like his hat?
And will any more general gameplay details come to the fore here? Because at the moment, we don't know how the game's been structured at all. What do you collect to open new levels and reach the final boss battle? Do you collect anything at all? Just how open ended are these massive levels anyway?
All of that's unknown at the moment, and it makes you wonder whether Nintendo will shed a bit of light on it in this event.
So what do you think? What will Nintendo show in their E3 trailer for Super Mario Odyssey?
