So are there any predictions as to what the flood is going to do in the long-term geographically speaking? Is the extra water just going to flow out into the Arabian sea sweeping everything with it, or are the current rivers just going to be permanently engorged with widening of the river banks? Because if the latter is the case, those villages that were on the rivers are gone forever.

Most of the villages I believe were on the river banks formed by previous floods (whenever there was flood like this before).

Historically the river Indus has changed course. I think with the way the flooding was this year it would almost certainly have changed course and created more damage had it not been harnessed by the numerous barrages, dams, canals etc. The Indus has been tamed to an extent.
Large areas will be under water for a while. New wetlands will be created - good for migratory watefowl from Siberia. The extra water would enable them to spread out more and the pressure from poachers and hunters will be less.
The villages on the river may have been temporary - some were but not sure about all. The people will be nomadic - they would have never had much so never lost much.
