It's always like this, I mostly see this in Melodifestivalen. Somebody goes up on stage, delivers a fantastic performance, is predicted to win until the next week (in this case, Thursday) when someone else is gonna do just the same.
I think Russia is absolutely going to be in the top 3, but they are not going to take the trophy. I also think that EBU is a bit scared that Russia is going to win and host with the political and HBTQ issues that will follow with hosting, same goes for Azerbaijan. So far I think it's between Sweden, Italy and Australia. Estonia, Russia, Belgium and Azerbaijan can however pull of a win. I truly believe this is a year where the juries will be united and decide the winner and the televoters are more split.
