Data miners have already managed to compile the remaining list of loading screens for Season 9. With 4 weeks left, all of the loading screens have been leaked. After this leak, we can easily designate the future secret Battle Stars, Banners or Fortbytes.
Below you can find 4 of the loading screens which are hopefully placed in the right order. The certainty that every picture comes from the right week is a bit compromised. They may be guessed right, but could also be shuffled. Therefore, do not take this for granted as they may be slightly mixed.
Hopefully, the loading screens are in the right order as we can already see some secret Battle Stars. The Last week there was no secret battle star so it is expected this week to have a secret battle star. The first picture somewhat proves that could be from Week 7, as the third picture also proves that it is from Week 9. Therefore, this indeed may be the right order.
