According to some Snowing fan online appears that Gosh told some fan when they meet her in Vancouver that if a s7 existed they would not be on it, which without proofs and taking in consideration this is ouat fandom,may be true or not.
Also,we have to take in consideration, that negotiatons, don`t mean the 4 will return, negotiations, means exactly that, negotiations, not confirmations and this negotiations may determinate the others, for example, lana staying could mean maybe Bex could stay as recurring, Bobby staying coud mean emilie as recurring, until official confirmation, all these articles, fans and paps are in limbo, may be true or may be “alternative facts”, specially also depending on ratings for the rest of season.
