it did but depends on what your comparing; units vs overall sales. overall, gross sales it killed everything in revenue generated due to the fact that video games are that much higher priced than other media.
btw, i didn't buy Modern Warfare 2 and never said it was awesome just that the claim console video games are dying is absurd. if anything, its growing due to the casual market. us core gamers have always been a given but the casuals bring another sect to the game. sure, they won't buy games like us core gamers but they still buy games and were consumers that prior to this generatio may have never bought a video game (ie wii market).
