So they're going to announce the price about 15 minutes before preorders go live, right? If they haven't said it by now, they must be waiting until the final possible moment. I'm not 100% certain what that ultimately means, but I'm not a fan.
You load the preorder site. You see the price. You decide whether or not to click "Buy" based on that. I don't see what the problem is. You're not being asked to make an uninformed decision.
