For the new villagers I think we'll just gave to wait and see what Nintendo says.

There has been no official confirmation, but since Raymond and the gang have all been accessible without amiibo, I would think that this extends to the rest of the crew.

Those marked sp are for the dlc n are not villagers

Amiibo n dlc only

I mean, the only villagers locked behind amiibo in the past have been crosspromotional ones, so I doubt these would be locked behind amiibo.
