Let me say this: I've never read anything by him. So I shall neither cheer nor grumble. I was betting on Ngugi or Transtr?mer. I noticed that he wasn't mentioned much during the last hundred or so postings on the Nobel Speculation thread. It would be interesting to look back at that thread, now it is closed, and see who made the most perceptive comments about him there. Regarding oneself as a genius because you said somewhere that a Latin American author would win is not quite enough to get you a prize for looking into the future as a soothsayer.
Anyway, I hope this Peruvian who is a Spanish citizen and teaches a lot at Princeton University is a worthy choice. I imagine so, but as I've said, I've never read anything by him.
