NIL will change CFB more than anything, there's already a booster wanting to pay Caleb Williams $1mil to come to E. Michigan for a year.
The lightly attended bowls have been that way for years, before the playoff came along. They have always been tourism drivers for the teams involved and I don't see how expansion makes that any worse, nor do I think it will affect TV ratings. It will definitely keep more of the best players in the games instead of skipping.
Really hate what happened to Corral, and that's why a lot of guys skip if they're going to be upper round NFL picks.
Also hope they settle on 8 teams to expand, it's the best option to me (could be P5 champs, best of G5 and two at-large, but they'll probably go with selection committee picks for top 8 which is fine too). You add one week and four bowls, and it means all the top bowls get playoff games every year. 12 is too many but I know they want that TV money.
