It's more of a modern issue, but I recently discovered that a lot of triple A console games are demo'd (at trade shows and in promo videos) on a pc. They then cut down video quality and content to port them to the console game you can actually buy. There's video of a pc hidden under a desk, and a console controller modified to work with it.

It may be old news to a lot of people, but that blew my mind. I don't see how that is acceptable. I guess that hardware for these consoles is still a struggle.
