Sony and MS could and will really make the next jump a lot cheaper entry for them. Not having to reinvent their whole online world. But if they were super smart they would just upgrade their processors but keep 100% compatibility. This way there isn't this huge start up cost that every gen prior has had. At that point there is no reason on the horizon to ever stop. And to the article, for Sony the play station division, even though it's been down lately is way too much of the company imo to walk from.
