While I agree given a choice I'd take improved gameplay, I think the value of immersion can't be overstated. I was looking at a few of my full game video captures form lastgen NCAA Football and presentation is NOT better in nextgen. Lastgen featured more relevant comments, conference standings shown before the game, and pregame graphics showing the announcers and even Corso's pregame mascot head. The overall atmosphere is worse now than it was 3 years ago on NCAA 2008 for the old Xbox. It has not gotten the attention it deserves.
I'd say go back to the PA Announcer ONLY for non-televised games, and add a second "regional" broadcast team for regionally televised games. Then add a whole lot more for them to say, and add way more context sensitive things to say like specific comments on the players and teams, how they're doing, the importance of the game, etc etc. Oh and lastly fix all the bugs where the commentators say wildly incorrect things. I see way more of that now than in lastgen.
