The Saudi's have played footsie with the true amount of their reserves for decades....( and for their own good reasons).....and no matter what, I predict they will make this so it "appears" to be transparent, but it will not be.  I for one will not and would advise everyone not to be a partner/shareholder with the Saudi Royal Family.  You can't pick your family, but . you CAN pick your business partners....they are not a pick i would ever make.
