I am expecting her getting her ass kicked and be gone to Bellator.
Amanda Ribas will win this, and it won't be particularly close.
Van Zant essentially quit fighting years ago (Injuries, stoopid Instagram naked pics more worthy of her time).
Amanda Ribas is a terrific fighter, skilled, athletic, trains hard, fun as hell, great personality. She's just an entertaining exuberant fighter
I'd honestly say of the "new-ish" female fighters, the 4 that get my attention as far as excellent prospects and all-round fun-factor are (in no particular order):
Amanda Ribas (115lbs) (already beat Randa Markos and MacKenzie Dern)
Mariya Agapova (125lbs) (very impressive performance on her debut -- definitely a future star IMHO)
Julia Avila (135lbs) (should be ranked now, she's exciting & powerful - goes for finishes, & 135lb division NEEDS new blood)
Yan Xiaonan (115lbs) (5 UFC fights, won them all)
