this boat looks just like the other boat, costs just as much as the other boat, except the other boat actually performs better.
I think you're putting way too much emphasis on this single issue, probably because of some personal disappointment.
Performance and image quality problems in multiplatform titles have not killed the PS3, and they won't kill the X1 either.
Exclusive games and services are also very important. Microsoft has a lot more money to spend and their 90 minute E3 show seems to be all about games, suggesting that they have a lot of releases coming up.
Sure, the silence from Sony may indicate confidence that they don't need to hype up anything... But the news about studio closures and reorganizations, about canceled titles and such are making it much more likely that they're not in a good position.
Neither consoles have a real nice system seller on the horizon so far. If MS is the first to come up with something truly nextgen - and not just graphics! - then it should be more then enough to compensate for the weaker hardware.
After all, Ryse has already demonstrated that capable developers can build some really outstanding titles on the X1 platform. 900p with an effective AA solution is perfectly good image quality, so it's "just" the gameplay and the content variety that's lacking, and it can be built with enough time and money.
