If by "classic editor" you mean the source editor, they are not getting rid of that.

Use Special:Contact and ask Wikia if they are going to focus on Template creation in the new VisualEditor and see what they say. They haven't said they are going to make that work any time soon in the related blog or forum posts they started.
