Laura Thalassa's Four Horsemen book covers

I saw some of the new book covers coming out for Laura Thalassa's Four Horsemen series (Pestilence, War, Famine, and Death), and I'm wondering if I should make a mad dash to buy up her books and audios so I have a copy of the original covers with men on them. I don't usually buy the physical books.

I'm a bit worried about all the covers switching. Last time, I was disappointed when Carissa Broadbent's Slaying the Vampire Conqueror book cover changed, and then the only cover I had that was the original was the audio version because thankfully I bought it. The Kindle version just suddenly changed covers, and I lost the picture.

Anyone know anything about the Laura Thalassa's Four Horsemen's book covers and what I should do?
