It might be worth to look at it if only to check whether there's talents that still there or not. I said this because if anyone recall the last Koshien, there are talents who said not to let them be drafted into the rosters and turns out to be already in process of leaving. Granted that it's a bit of a reach, but if you're into that, its there.
Aside of that, it might interesting to look if only to see how they gonna do it now that they have JP-speaking EN talent in it. Who knows that maybe one of them VTA draft-dodger ended up acting as a coach?
