Is there an Unlimited format coming?

I spent quite a while building a card collection in TCG Online, though I took a break from the game for a couple years. I always played in the Unlimited format, because it was the only viable play style for a casual player like myself. However, after migrating my cards to TCG Live, I found out that a huge proportion of my cards are banned, so I can’t even use the cards I migrated. Will an Unlimited format be coming? If not, please consider adding it, because I fee very cheated without the cards I worked hard to get.
