I think that giving people 2/3 extra votes and all that makes it over complicated. If everybody just has one vote (including the winner) then we can just have a simple poll which can be reveled once the voting is over.
The winner of the previous edition could perhaps decide on the host country, host city and hosts of the next edition, but I dont think they should have any more say over what the actual edition is.
It is by country just like the previous edition!!
It will be first come first serve, I guess~~
So if you're thinking of US TV shows, you better act fast!! XDD
