Byron Wien CNBC Blackstone Vice Chairman Byron Wien is out with his highly anticipated list of 2012 surprises.

The predictions run the gamut, from a renewed Arab Spring to a revitalized American Economy. He even weighs in on the Euro debate.

This is the 27th year Wien has produced the list, which he started while chief strategist at Morgan Stanley in 1986.

He notes that any given prediction has only a 50% likelihood of occurring. Last year that was the case when he predicted an improved housing picture and gold topping $1,600 an ounce.
