Not comparing Apples to Apples…
Yes, Jodie Williams looks like she will be sure Olympic runner, but she will also be 17 years old next month.
To fairly compair her to Hannah, you will have to match their performance with the age level, which would take you back to her performance in 2007, the year she turned 14:

In 2007: Jodie willams best 100 meter dash: 12.01/11.85w best 200 meter dash: 24.77/24.57w
In 2010: Hannah Cuniliffe 100 meters: 11.71 (USATF Nat. prelim) 200 meter dash: 23.91 (USATF Nat. prelim)
So, if you compare performance at the same age, looks like Jodie Williams has some competion approaching…as Hannah is significantly faster at the same age.
Anything can happen…who knows…but to compare a 14 year old sprinter to one who will turn 17 next month, is not a fair comparisonl.
