Wii domination will not affect games in general. While it might create new genres and spark creative ideas, I do not think it will drastically affect how hard core games are made, nor how they are sold. The definition of a casual gamers is that they don't play games that often. They don't get into deep. The only thing that opening up the casual market does is to bring in more potential hardcore gamers. That is the blue ocean strategy in a nutshell. Granted, games like brain age on the ds will sell well (mostly on the back of sudoku, i might add), but that doesn't mean that games like New Super Mario Bros doesn't sell just as well. Wii is a home and a haven to many hardcore franchises. Metroid and Zelda are by no means "pick up and play" titles. And while the basic mechanic of the new Mario may be, the conquest of the game as a whole is an experience only suited for a hardcore gamer. What may change, however, is the style of hardcore games. I don't think we can assume that Gears of War is a game for hardcore gamers, while Zelda is not. If "hardcore" is being used to describe the mature content or style of a game, then you are probably right. The Wii certainly could fail. I don't think that that is a fair definition of hardcore, mind you.
