Question about Cataclysm

Hello, I would like to know if there are any plans, or possibilites that we could see the opening of a progressive Cataclysm realm from Warmane in the near future? The reason I am asking this is because Warmane once used to run a Cata realm, and, while it had its bugs and issues, was very fun. I am sure it can be delivered in a much higher quality these days, and there are many who loved that expansion, including myself. And if such a realmwere to exist, would it be in the Icecrown format(high rates,shop) or the Lordaeron format(blizzlike 1x rates, harder raid content). There is also the issue of WOTLK Classic coming in 2022 probably, so a simple answer would be much appreciated.Thank you in advance for answering.
