She has already won a senior title. I don't think she has been overhyped, no one has said she will definitely win a GS. It think it is almost certain she will be a top 50 player, but very difficult to predict how much further than that she can go.
she has indeed - I watched her do it... She definitely has the skills, although it is definitely early days yet. She seems pretty down to earth though, so it obviously hasn't gone to her head yet!
