I have hopes:
If Retro is shown and looks good/up my alley, points in my good book. (I think if 2018 games are shown, this is a more likely one but it may be something I'm not sold on).
If Metroid is shown and looks good and proper, many points in my good book. (I can't be sober about this. I always foolishly half believe there'll be a Metroid announcement).
If Fire Emblem is shown and looks to be a return to form wrt story/characters/world, many points in my good book. (Again, a more likely 2018 showing but given recent expanding on the benefits of "console" FE, I don't think IS means what I want them to mean.)
If varied Japanese support is shown for 2018, ranging from PS4/Switch multiplatform titles to 3DS successor titles (like, say, an Ace Attorney game), many points in my good book. (Japan seems like it was quite wait-and-see on Switch/over-invested elsewhere and tends to be slow to adopt anyway so I can't expect much here, even if 2018 games are shown).
If Atlus in particular shows off JRPG(s) looking like 2018 or so, many points in my good book. (SMT Switch looked far off. Unclear how much is going into these late 3DS remakes).
And I think some of these are more likely than others but none of them is something I'd count on happening.
Throw in Nintendo's announcement habits, which have in recent history failed to excite me, and even if they turn out to have these games, Nintendo might not announce them yet.
And then throw in the fear of a monkey paw, which is a very real possibility if, say, Metroid does show.
