I'd mostly want Nintendo stuff. maybe confirm if N-Stars is either a Mario Party/Amiibo Festival spinoff (supposedly Stars is a codename used for MP titles) or if it's a Dynasty Warriors spinoff (think Hyrule Warriors) featuring Nintendo characters with only Amiibos as optional temp-unlock/early costume unlocks. maybe talk about Zelda U and show something about Pikmin 4 since the last thing we heard was a vague reference by Miyamoto...how about that rumor that David Wise was doing a project for Nintendo? in N-Stars' case, they could vastly use the Smash cast if they wanted to, or pander to fans slightly by using characters that hasn't seen much use in recent years. you know you want to see Fire Hand Mario/Electro Hand Luigi as focus moves, heck, if they can figure out how to work in Paper Mario/Mario & Luigi characters, that'd be pretty sweet. even if Paper characters would be incredibly jarring, at least King of Hyrule/Tetra/Toon Link retained their proportions/graphics. I mean if Yo-Kai Watch and Zelda can have a DW game, why not Smash/the Nintendo mythos?
Otherwise, could always use a Dragon Quest Heroes 2 world footage reveal, a VII European date and if the rest of the world is getting Joker 3...or if we're missing out on them again just like the remakes of DQM 1&2, and Joker 2 Pro. Pokemon Sun/Moon would also be adequate...assuming they just don't reuse facts mentioned by CoroCoro or have videos...that's already been seen as if it's a major revelation.
