Will the ceasefire in Gaza hold?

Right now hostilities are scheduled to begin at noon on Saturday. All reports are that they will be particularly intense.. My supposition is that they will start in the north and be followed by ground forces as the process moves the population ever southward.. The ground forces will mop up militants and remain in place as more forces advance.. this time I expect all power, water, fuel and food to be shut down as the process moves southward.. . this will culminate with the expulsion of the population into Egypt after checkpoints have been cleared there....
