Excellent news. I now modifiy my prediction to be firmer.
Nearly ALL of the Sunnis will join up with the new government that has them represented proportionately to their population. Sunni support for the insurgents will evaporate and Sunnis will turn in the Al Qaeda groups operating from their neighborhoods. Al Qaeda attacks will therefore diminish into insignificance.

Nonetheless, I am on record with the above prediction.
