This project is most definitely going to be dead. 1: it's extravagantly expensive. 2: there's no "need" for it to be built. 3: Nakheel's bankrupt. 4: Sheik Mohammed has already fulfilled his dream of building the tallest structure on earth in his emirate. His ego is sufficiently padded, I'm sure. I think that sums it up
If it goes forward I'll be shocked.
