Welcome to the future of the gaming industry. This is going to happen again, and again, and again, there will be critics of this who will keep shouting out "STOP!", but literally millions of customers will preorder the games anyway. I'd bet a large number of the preorders aren't done based on the trailers or footage or other reveals, but just done based on just plain liking the idea of the game and not particularly caring about anything else. The idea of getting a preorder bonus might convince some people - who were going to get the game anyway, regardless of what controversy came out over it - to preorder it when they might have waited for it to come out on the shelves instead.
The only thing that's going to stop this sort of idiocy is for people to simply stop buying the games. Not just stop buying the preorder, stop buying them entirely. At least in the first month of launch, when the numbers matter. But since that's not likely to happen...
Ah well. Maybe the industry will crash again, but I don't think that's really going to happen unless there's a huge recession in the USA or Japan that seriously impacts everyone buying entertainment like games, movies, books, music, etc. It's not going to affect just the game industry - the industry is just too big for that to happen. Maybe a single AAA studio might go under, maybe two, but not the industry.
