No date announced yet. No English language article yet, but here is the Natalie source (edit: Anime Corner article). This announcement comes as the finale of season 1 just aired today. Synopsis for season 1 from AniList:
Lawrence is a traveling merchant selling various goods from a horse-drawn cart. One day, he arrives at a village and meets a beautiful girl with the ears and tail of an animal! Her name is Holo the Wisewolf and she brings bountiful harvests. She wishes to return to her homeland, and Lawrence offers to take her. Now, the once-lonely merchant and the once-lonely wisewolf begin their journey north.
I’d say it’s fine to skip the original as like you said, the final arc of it will likely be covered in season 2 of the remake
