The changes are largely to do with checklists. Airbus are trying to make pilots think, not read and do. Checklists will be reduced to just what will kill or injure. eg. after landing checklist is just radar OFF (except A380). Nada mas.
The rest of it you will have to remember and THINK.
That said, there's nothing stopping a company from keeping what's currently there, if they don't think their crews are up to it.
Briefings are also going to be kept BRIEF. Almost everything will be done prior to the brief except what we're going to do today that's different, and out EO SID. And some SOP changes to keep fleet commonality.
There are some good videos of the rationale and plans AirbusWorld if you have access
