Well, teams on a very close level participate here, so anything is possible. To be honest because of many reasons i didn't really have the time to watch womens EQT ( that's part of why i am now trying to catch as much women's games as possible ) besides Polish matches and the final, so I don't really know how the Dutch/Italian players performed there, but I really wouldn't be surprised if at least one of them wouldn't manage to qualify, as especially the Asian teams play on really high level here, so i Too think Thailand / Korea can be a very dangerous opponents to everyone and qualify to RIO. And Asian teams are typically good at women's volley ( China, Japan, Thailand, Korea are all really good )
TBH right now I think it will be Netherlands who has more chances of failing to qualify then Italy, not only because of today's match but also because some parts of their match vs Kazakhstan and the set they lose there proved something might not be right with that team
