This sound more like TreeHouse than Nintendo Direct.

I hope there's a new build of Xenoblade 2. Feature wise I'm good with what they showed at E3 but even they admitted the game was still being polished graphically. Assuming the E3 build was an older one by a few months I hope they managed to make a new one to show off graphical improvements. They need to show that if that game is really releasing this year like they keep claiming and they want it to do well. It can not look worse then Xenoblade Chronicles X which looked great.

If they need to delay it so it looks better I don't think many would be surprised or complain. I'd rather it be delayed then rushed if they do indeed need more time to make it look better.

In for more XC2! Apart from music, we haven't heard much of the game outside of E3, which is weird because I though they would use the XCX model of small updates. It may be more of a Nintendo thing in that they want every game to have a controlled flow of news to not interfere with the others in a packed schedule.

Can we expect something important here?

No.

I hope they show the second Zelda DLC.
