It will be repaired. Airbus have to create a repair scheme for the damage. You understand that it is a new aircraft and all damage scenarios have not been considered. This is not like your car. The repair they do will have to last for many thousands of hours and cycles.
When Boeing and Qantas repaired OJH in BKK it wasn't as though this was the first time a 747 had overrun a runway. They had a lot of previous experience. OJH is still a very good aircraft and just as reliable as the rest of the fleet.
