We have no confirmation on whether or not they will get Samui and Omoi in gnw treasures but I would guess not. Unlike China, they are recruited at three star in our regions instead of two. I would be surprised to see any changes made to gnw treasure in our version. in other versions the edo tensei treasure ended up becoming split into two treasures but they remained intact and as far as I know, our version has never made such large changes after the release of a treasure. Could totally be wrong but hope I was helpful.
