The airport is unlikely to open until at least November at this point, but it could be December or even 2014 at this point according to what you believe.
The Wizz agreement with Chopin, according to some respected Polish language sites, has a clause that should Modlin open before the 26th October they will switch back earlier than this date. Both airlines it would seem are committed to returning to WMI when it (eventually) reopens.
Ryanair are no doubt going to extend their presence too, they most likely want to understand how long it will be best to do so. Ryanair were first to extend with Wizz following a few days later on some occasions, the opposite on others.
I doubt either carrier is particularly happy about it since for the airline it would be much more expensive to operate at WAW. Sure Wizz operated there before, but when they did so they had no competition from FR. The competition has pushed Wizz prices down and FR has been selling tickets at very low prices too so I doubt either airline was on a high margin at Modlin, let alone at Chopin.
