These are the same bishops they trotted out last time.
“They” is the bookmakers, not the Vatican. I’d be surprised if it was any one of these.
BXVI has appointed a number of new cardinals (from everywhere), so that the majority by the time of picking the new Pope will probably be pretty conservative. Beyond that, I don’t know.
I do think it may be an English-speaker, but that could be anybody from a Brit to an American to an African to an Indian. I don’t think it will be an Italian, no matter what.
“Trotted out”, that’s a funny way to put it. Makes me imagine the bishops are stored up in the attic, with dropcloths over them to keep the dust off until it’s time to pick a new pope.
