My understanding is that most of the money was in legal trusts. In that case, the trusts would go into the control of whomever was listed as the custodial beneficiary for the trusts, which I'd be willing to bet isn't Anna Nicole. The son's estate will probably be held up by the ongoing litigation.
IMO, Anna Nicole got what she got. Just because she thinks she deserves more doesn't make it true. Her late husband was reportedly a very shrewd lawyer who handled trusts and wills for a living -- if he intended to give or leave more to Anna Nicole, I'm sure he would have done so.
