I think actually Aaron has hyped up people more by saying he won't temper expectations because he usually does that every year recently, in comparison with Sarah who is far less known than even Aaron (200,000 less followers) and while she is hyping the showcase up, she is also playing on the meme video of her saying "Games/Gaming" a hundred times, Lol.
But Aaron's refusal to temper expectations even after saying he's seeing all the hype is more interesting to me than Sarah's "games" spam. Whether this meets expectations or not, Sarah should replace Phil in the future but it's hard to promote her when she's already essentially one below Phil 
She'll have to wait for him to step down but she's certainly making her presence known more in the community the past year or so.
