No more buying every new game that comes out, only get the 1 or 2 big games that come out. It's software sales that make a system sell, and if people only buy 1 or 2 games a year, then the system isn't going to do very well regardless of how well the games are rated.
And if this happens, I fully expect 3rd party developers to shift games to the Xbox 360 and Wii where prices will be more normal, even though 59.99 for a game that is nothing but a glorified port of a Xbox and PS2 game, right now, is a little much to swallow.
I expect, just like this round, I will buy more Nintendo system games than I bought for PS2, or Xbox (I have only like 4 Xbox games).
