Note: These articles are more for discussion purposes before E3. They'll be short, sweet, and to the point for a brief recap and looking into possible characters/stages for each series in Smash Bros. These also go by a "Don't expect too much" philosophy. Please remember to be civil in the comments discussion.
Animal Crossing's introduction in Smash was an interesting case - it had one stage in Super Smash Bros. Brawl but no characters to go with it. Afterwards, the series received one character in Super Smash Bros. for 3DS and Wii U along with one new stage in each version, as well as the return of Smashville in Smash Wii U, bringing the total to three.
Returning Characters
Villager will most likely return; I'm about 99% positive on that one.
New Characters
If Animal Crossing even gets a second character, Tom Nook seems to be a likely hook for that. Isabelle and KK Slider are also candidates worth considering, especially given Isabelle's popularity. It's doubtful that the series will have a new characters, but it's also a pretty beloved Nintendo franchise, both in and out of Smash.
Returning Stages
Smashville or Town and City will probably make a return.
New Stages
Something from Animal Crossing: Pocket Camp or possibly a future Animal Crossing on Switch seem plausible.
