I just signed up after lurking the hype thread(s) for three full days.
I had pretty low expectation for this Direct, but I'm still mostly disappointed. For reference, I was expecting firmware update, Kirby, Yoshi, Octopath, a Wii U port, an indie sizzle reel with around 6-10 games, Dark Souls, and at least a cinematic for Fire Emblem. This is somehow more underwhelming than that. Maybe I just happen to be the exact wrong audience for pretty much everything announced today. I really wish the Mario Sports game had ended up being Strikers. It's not only (probably) the best of all the Mario Sports games, but it just makes sense in this particular year, what with the World Cup and all. I will probably finally end up playing TWEWY after years of being guilted into it, so that's cool.
My biggest takeaway is the absence of Fire Emblem. The fact that it wasn't revealed probably means that it's not coming out until Q3/4, and therefore it will probably have a huge presence at E3. I don't think FE is hot enough to prop up the latter half of the year on its own. Hopefully Smash and/or Animal Crossing are announced alongside it.
