A year's delay after IRA move?

Brian Feeney reckons that whatever happens, the DUP will not be going into power with Sinn Fein until a good year after the expected statement from the IRA accepting Adams’ initiative outlining a politics only way forward to the whole Republican movement. He also points out that whatever Republicans make of the IMC (even the DUP was lukewarm on it at the time of it’s establishment), they will have to get through a year of positive reporting before anything moves.
