I feel like a lot of publishers are playing it safe and are designing games that appeal to a very specific demographic so that leaves us with a lot of different things to be desired. Though I don't think there's going to be some sort of "crash" because there are a lot of gamers out there but not enough to blow every budgets out of proportions to create uninspired games.
Edit: "it is an unfortunate fact of life in the world of entertainment that the unique is rarely successful, and the successful rarely unique. And when the great God Cthulhu in his cosmic thrown crosses his legs to sneak one off causing the stars to align and allows something that is both unique and successful to come out it all but guaranteed that it won't be remaining unique for very long because the imitators will arrive bringing golden calves to worship while Moses...." You get the picture.
