gw2 heart of thorns

Hi, I saw that there is an option to buy heart of thorns addon from epvp store. How can they put a price 42.50$ on this addon if the price is not announced yet?
I would like to preorder but i'm not sure is this legit. Did anyone buy it?

It's a scam. They can't know the price know. Anet has not announced anything like that, so it's not legit, no.
