Pretty indifferent about this. And really, when you look at it, series with silent protagonists tend to do pretty well, wondering why that is. Pokemon, The Legend of Zelda, Jak and Daxter (at least for the first game), and several others have gotten pretty popular. So really, I think it'd ruin the sense of the games a bit, since you're supposed to be the protagonist after all, the choices are all yours, and I'm guessing that's kinda what they're aiming at here. I just don't think pre-scripted dialogue for your very own trainer kinda fits into it all, but yeah, that's just my opinion.
