New event theory

Hi, after seeing the leak of the new golden lootboox I formulated a theory for the next event: I think that blizzard will allow us to buy old events skins at a bigger price (maybe 4000 gold) and these lootboxes, once open , will give us gold. I think this event takes less than the previous one and will be repeated once a year. I hope my theory would have liked you, I wait to read your opinions
