Abu Dhabi bailed out Sheikh Mo and took overall ownership of the profitable parts of ICD Investment Corporation of Dubai. That was the only way Dubai could offer collataral for the loans of $20 billion. Sheikh Mo was utterly humiliated at the forced re-naming of The Burj and left within moments after the opening. Also how could Dubai raise the money to buy EY? Massive regulatory hurdles abound. Not to mention egos higher than Burj Khalifa. I doubt thus will happen.....
