I wonder if there's going to be a news report after every gym challenge with battle highlights and polls on who people think is going to win the Champion Challenge or ratber the favorite to win. I doubt all of them will be required to watch, if anything the rivals will mention it in passing, but I think broadcast 1 and 7, (8 if the final fight happens after the league), will be required viewing. Might look a bit like this.
pre 1st gym: Hop 50%, Bede 50%, Marnie 0%, pc 0%.
1st gym: Hop 45%, Bede 50%, Marnie 0%, pc 5%.
2nd gym: Hop 40%, Bede 45%, Marnie 5%, pc 10%.
3rd gym: Hop 35%, Bede 40%, Marnie 10%, pc 15%
4th gym: Hop 35%, Bede 35%, Marnie 15%, pc 15%
5th gym: Hop 30%, Bede 25%, Marnie: 20%, pc 25%
6th gym: Hop 33%, Bede 15%, Marnie 25%, pc 30%
7th gym: Hop 33%, Bede 1%, Marnie 33%, pc 33%
And the eight gym is the same, people think Bede can win he's just become an unfavorite amongst people
