Without saying too much, I'll just repeat what I said the other day in the Geno thread. Most of the rumors that have come up since last summer is that Nintendo is going to try to fulfill a lot of long time fan requests in 2020 so a good number of series will likely have "consolation prizes" announced by the end of 2020 if Nintendo doesn't do this through Smash. Obviously, not every Smash fan request is going to make the cut but it seems like Nintendo is conscious of this and going to try to make it to people but in different, and even arguably better, ways. For example, Panel de Pon is, from what I've heard, just the beginning of Nintendo doing things they've seemingly ignored for years.
