They will not. They have been confirmed so many times if they have no money left for the refund or burn and why are you still asking the burn when you know that luna team has been saying about that so many times? i know that people will not believe with what he said but again they the only party who knows what happened with whole of funds from the bitcoin reserved and so it's pretty much useless to talk about that.
Im sure that they will be forking this blockchain as soon as possible rather than taking the new blockchain.
