Well it's obviously possible, but how realistic is it that Ashley and Mai place out of top 6? That both Kaetlyn and Gabby hold it together well enough to both make top 6?
I think it's highly unlikely that both Canadians will make top 6. But they're more likely than US and Japan to get three spots now, that's for sure. Which is so darn weird and unexpected (but good for them!).
Without Satoko, Mai and Wakaba (less so Rika) are going to be under huge pressure. I hope they handle it well.
I think a most realistic scenario would be...
Top 4: 2x russians, canadian (lets say osmond) and Caro - in some whatever order.
Then, there will be a crazy fight for 5,6,7,8 because those ranks are the ones that give any chance for 3 spots next year.
Now, its possible that we have, in 5-8, something like: 1 russian, 1 american, 1 japanese, 1 canadian.
How likely this?
Well, i´m basic myself on top scores in 2016 now. Taking out juniors and whoever doesnt go to worlds, we have:
top4: Medvedeva, Pogorilaya, Osmond, Caro.
Then, we have (in this order): Mai, Sotskova, Daleman, Ashley.
So yeah, looks like Japan and USA losing 3 spots could be possible and not very unlikely.
