I think this would have happen by 2030:
Portugal, Armenia,
Azerbaijan, Georgia, Croatia, Bosnia & Herzegovina and Iceland will all have won ESC for the first time.
Russia will win ESC two more times. Ukraine, France, UK, Sweden, Serbia, Denmark and Turkey will win one more time. The other winners is more uncertain.
Italy will jump back and forth in the contest, but will in the early 2020s start to compete every year.
Montenegro and Czech Republic will come back to the contest. Liechtenstein will debut in early 2010s and Kosovo will debut in late 2020s.
ESC will change the rules to allow pre-recorded backing singers and allowing 8 people on stage.
And Asiavision will have started by late 2010s!
