We can expect the same high abstention rate. Iranians also sometimes have this opportunity to demonstrate their dissatisfaction with this regime and show that they no longer consider it legitimate or, above all, representative. It is therefore possible that Iranians will not go to the polls. This is one hypothesis. It's also possible that this will lead to other types of demonstrations.
The main question for the weeks, months and even years to come revolves above all around the succession of the supreme leader. Supreme Leader Ali Khamenei is old, and is thought to be ill. President Raisi was a possible candidate, the assumption being that his position as president was a stepping stone to the supreme leader's seat.
The whole debate will focus more on the succession of the supreme leader than on the elections. Indeed, we know that, in the end, it is the supreme leader who has absolute power. He delegates responsibilities to other organizations, but he holds veto power at the top of the hierarchy, which is very pyramidal as far as institutional power is concerned.
