I think everyone's so antsy about review scores because we're coming of a slew of games that reviewed very highly. Zelda, in particular, is one of the highest rated games in quite some time. I think people treat review scores like a commodity and want to see this game they've been waiting for do just as good if not better.
The problem is, and I've mentioned this before, reviews are literally expectation vs. delivery. Expectations color someone's review, and that's a good thing in the context of someone describing their time and what they learned and didn't learn from the game. However, it makes comparing review scores virtually impossible.
P4 and P4G were gateway drugs to Persona for a lot of reviewers. They had no expectations going in and were blown away by the level of polish and detail. Small issues like plot lulls, dungeon design, and certain character quirks were ignored due to the sheer impact the game had on a lot of reviewers. The same is somewhat true for Zelda, which bucks long-standing trends and really gave reviewers no idea of what the game was going to be until it came out. The impact was visible.
This is why you see lines in reviews like, "It played it safe", or it's "more of the same", because reviewers are trying to reconcile what they're experiencing with the score they're obligated to give to the game.
All that said, the game's going to do score very nicely and I think people are basically worried about nothing because you're all going to come back here in two weeks with your own set of complaints and passion-points.
