Hardware competition doesn't breed quality. Developers breed quality. Whether we have 1 gaming platform or a hundred. We are not stupid children. The devs who pain stakingly strive for excellence will be the ones that sell above the other games.
Very much this. We need software competition, and we have more than plenty of it (and where it lacks won't be made up in the least with console diversity--quite the opposite). But the biggest improvements in gaming hardware are not germane to consoles alone. It's predominantly integration of other aspects of improved technology. Processing and applications will get better if we just WAIT by virtue of all the other industries in which advancement is truly critical and valuable. Active development towards consoles is for the most part more about squeezing the consumers than pushing the tech forward, and the primary exception to this are the things that many gamers dismiss as "gimmicky."
Any reaction besides what Major Nelson gave would have been seen as hating on PS3 lol. It's not how much exclusives you have. It's who makes the best exclusives. Software competition.
