I have not been following this story closely and I've never read Nyquest before. I followed some of the links in his article and on his site and found this (written back in October).
In this essay he talks about the political killing of an author and names Alexander Litvinenko as another similar author. He doesn't come out and predict AL's assasination, but considering what he was poisened with, I am now very intrigued:

The Assassination of Anna Politkovskaya
KGB-directed false flag terrorism in Chechnya has justified the re-establishment of dictatorship in Russia (see the work of former KGB/FSB officer Alexander Litvinenko, author of Blowing Up Russia)....
...The death of Politkovskaya is openly acknowledged in Russia as a political assassination. As such, it sends a chill through those who know the truth. Who will dare to warn the West in yet another book? Who would give their life in an appeal to the apathetic sneers of the indifferent?
