One of the most important determining factors as to when he dies (or disappears) is how soon he will be asked to testify. As far as I know, there is not even a subcommittee looking into this yet. So that gives him a little more time.
Congress has a lot to do with his demise. I'll be watching what happens there to get a more precise idea of when it is going to happen.
As of now, I chose within 6 months. So, he will likely not be around to see the New Year. But, again, a lot depends on what Congress does.
