Azshara Hero Portrait

Good day. Unfortunately, I started playing HS after the Voyage to the Sunken City expansion came out, so I wasn’t able to get Azshara’s shot on the mage, which I really like and want. I am also interested in the portraits of Vaish and N’zoth, which I would also like to receive. Tell please, is there a chance that it will be added in the future at least to the store, so that it can be purchased for money? And when can we expect it?
I read that the pre-purchase portraits haven’t been added to the shop yet, which is very sad. I hope blizzard fixes this.

Even though it doesn’t both me if anyone was to buy Lady Vashj (the only pre-order portrait I have), they are sold as exclusive to the pre-order bundles. So I’m pretty sure it won’t happen and I’m not sure they even legally could.
