Take a look at this amiibo chart published on Nintendo's Website. It's pretty clear that all Animal Crossing: New Leaf + the Welcome amiibo characters are back in Animal Crossing: New Horizons, but with a few exceptions.
- Sanrio characters did not make the cut (might be added later on).
- Non-canon Nintendo-related villagers that were invited by scanning Zelda, Mario, Splatoon amiibos (Ganon, Medhli, Wolf Link, Nene, Cece, etc.) amiibos are not back either.
I'm kind of glad the Nintendo crossover characters are not coming back (and hence are not canon). They felt out of place, weird, gimicky.
