I will definitely scan in my favourite villager, but otherwise, I'll wait to see who I get in game and what they're like. If I get attached to some new villagers and they have more unique dialogue, I won't move them out for amiibos. If I'm not a fan of them or they're more like New Leaf, where a lot of their dialogue is generic, I'll probably replace some of them because I can at least get villagers with designs I prefer who say the same things.
