Not a bad list, but I think Lopez (Spain) is fast enough and has enough championship round-running experience to make it through.
Olivier of South Africa has the speed and looked great in his heat, but I'm not sure he'll hold up to the rounds.
Symmonds unfortunately had to run hard in that brutal fourth heat, but I expect he'll find a way in.
Rudisha goes without saying.
Kszczot is incredibly talented but never seems to hold up well in multiple rounds. I expect him to disappoint, even though next year, he'll go 1:42.
Solomon is freaking me out. He's never been remotely this good. He's been transformed (by something). Should make it through the semis, but not necessarily the labs.
Aman and Kitum are very likely.
Kaki hasn't looked good at all this year, but suddenly looks great--another potential lab casualty.
Did anyone notice that Canadian, Harris? I had to look him up. He's absolutely terrible--to call him a career journeyman would be high praise. And yet he's through to the semis. It will end there.
