[2022] Living World Season 4 + Icebrood Saga

Does anyone know when LS4 and Icebrood Saga will go on sale, or know if they are ever announced ahead of time that they are going on sale?

Unfortunately, I missed the freebie LS4 login stuff last year and I'm trying to figure out if I should just buy them now or wait it out.

I'm sure eventually they'll be available again as a log in reward but that could be a very long way out.

I'd appreciate any help anyone could give me or point me in a direction I can find sale information!
