Will There Be More Emote Stickers In The Future?

Pretty much what the title's asking. While I'm impressed with what we have so far, I'm kind of surprised there aren't any stickers like a smiling or confused Braum, an angry Kled, or even an overexcited Ziggs in the list of emote/response stickers. I understand such things are probably at the very bottom of the priority list if they're even there at all, I just can't help but wonder: Will There Be More Emote Stickers In The Future?
