Speculation is that GOTY 2017 will be Gabriela McBride, an African American poppet who is styled after the recently retired Truly Me 46. Her rumored bio is that she is a tap dancer and owns a cat.
Very little else is known, but the silhouette above seems to confirm all those curls from the TM 46, perhaps styled up in a ponytail.
Her meet outfit seems to be a shirt with 2/3 sleeves, leggings, and ankle boots.
