Kazakhs now are firmly in the driver seat, no question about it. Strongest team, easier remaining opponent and 3 points of breathing room. Regarding Austria, I frankly doubt they are even close to Kazakh level and can hardly be labeled "main rivals".
They have a poor generation which had the benefit of playing Hungary and Japan in the first 2 games giving them optically imposing 6 points in 2 games. But the went to SO in pre-tournament against Hungary, had to score in the last minute to win it in the main tournament and then lost to Danes. They can hardly be called favorites today against France, very good chance the tournament is decided today.
