Enron looks to be to big for the normal "sweep in under the rug and wait for it to blow over" thing. This looks more like a "find somebody to pin all of the blame on" sort of situation. This is doubly likely because there are so many politicians involved who need to shift some blame off of themselves.
One of the Enron senior executives will be the one to take the blame if it goes this way. It will have to be one high enough that all of the blame can be put on them, everybody else can claim they where decived, mislead or ordered by this person to cover up problems.
Expect the target to get hit with some seemingly huge fine and very likely a moderatly long jail sentence. Seemingly because while a few million dollars may seem like a huge fine, for somebody that make tens of millions a year it's just a major inconvience. The jail sentence will seem faily long at the start, but a year or two from know it will be reduced to time servered and they will go home.
They will probably be able to recoup all of the lost money by writing a book in which they blame everybody but themselves.
