Turkson being the favorite early on was just nonsense, people making "fun" bets. Same thing with Peter being chosen as papal name. It has zero chance of happening, I think. Cardinals are way too racist for that, and Italians are way too many. I hope I'm wrong, as an African or Latin American Pope would be great, but I don't see it happening.
I think it'll be Scola, but you can never be sure. Besides, for this conclave we are back to the 2/3 rule (Benedict was chosen through simple majority), so if there is strong disagreement between two sides, they may choose something "in between" (whatever that means in this case).
I find this whole Pope thing deliciously anachronistic, sort of like William and Kate's wedding. Stuff that shouldn't be happening in the 21st century, so I like them (while being against them at the same time).
