The Animal Crossing team are the same team who develop Splatoon so AC can't really be out next year if Splatoon 2 has only just come out, the closest on that list to be out is Pokemon otherwise it's Retro's project.

Actually, it can. A ton of Splatoon 2's development most likely didn't even take a year, due to the base game already being there.  A ton of assests were re-used and so on and so forth. I'm confident they have had a small team making an HD Animal Crossing for quite some time now, and now that Splatoon 2 is out and was done probably mid-June, they're most likely well underway with AC. Plus, they're already used to HD development and the Switch, so unless they're making Animal Crossing open world, it is definitely entirely possible for it to be out next year.
