I tried.
Ran out of authors I legitimately thought could win near the end as I still doubt Mantel or Robinson will/have actually been considered. The same with Kincaid and Conde. Several of the older perennials I really don’t think have any shot (Byatt, O’Brien, Oates, etc)
2021: Annie Ernaux
2022: Can Xue
2023: Anne Carson (they reassess her and decide “why not?”)
2024: Friederike Mayrocker (a 100th birthday present)
2025: Han Kang
2026: Lyudmila Ulitskaya
2027: Xi Xi
2028: ?
2029: ?
I could easily see Mantel or Kincaid winning in the near future and there are so many women writers they could award: Danticat, Kareva, Erdrich, Hustvedt, Tawada, Egan, Ndiaye, Erpenbeck, Zadie Smith, Zeh, Adichie, Tolstaya, Ugresic, Belli, Krog etc.(I don't like every on of the names I mentioned, but I could see a case for each of them) The time might be up for Walker, Didion, Proulx, el Saadawi, Vitale and probably Atwood, if it hasn't happened yet. But they could make it a decade.
But I doubt they will and I hope they won't. That would diminish the prize and make the these prizes feel less deserved.
