Exactly!!!! I think the franchise is due for a more darker episode with the last 2 being Botw and SS. I loved Botw's artstyle and i think it's the best one yet for the franchise. But i just like the story line and atmosphere better when it's more creepy Zelda. I would be surprised if they do another cell-shading game since they like to change thinks up.
Well while it isn't creepy, what story there is in Breath of the Wild can be pretty dark. It's just the story takes a pretty significant back seat. I think a Zelda that zooms in on that more serious, occasionally grim tone with a greater story focus while retaining the more freeing gameplay of BotW would be a great way to follow up on BotW.
