IMO the plan is to make the Gazans so miserable they leave, but unless some other country takes them that is a dead end, so perhaps that's the plan instead, now.
Then, as IMO the israelis are provoking the West Bank Palestinians into an uprising, Gaza solution to West Bank Palestinians.
If the world's leaders finally wake up and stop that, I suspect the israelis want to return to what it was before, but maxxed up control. Get rid of any Palestinian authority and direct rule. Occupy Gaza. Perhaps deport them to the Sinai to live in American style reservations. I doubt the Americans could or would complain about that, given it's what they do.
However, there is a long way to go, and thousands more Gazans to die before it ends, so who really knows what will happen, despite any plan?
