First party : -Smash blowout, but it's not totally a new game, kind of in-between a port and sequel. The amount of content taken from Sm4sh is more than commonly expected. - Yoshi release date and new gameplay trailer - Fire Emblem reveal. It doesn't look very ambitious, a very standard Fire Emblem except this time in HD. Big, controversial focus on waifus. - Mario Tennis Aces new trailer showing more of the Solo content - A new Wii U port is revealed
Third party : - Fortnite - Octopath traveler new trailer, quite hype.
That's the least I expect - any less and I will definitely be shocked and disappointed.
