Everyone thought this when the XBox came out. Then again when the XBox 360 came out. Everyone laughed at the fact that Microsoft didn't include a Bluray player. Now it isn't even a battle between Sony and XBox. Xbox has crushed Sony.
And that is why I'm hesitant to run out and buy a PS4. Right now on paper it seems like the better system. But the same could be said about the PS3.
Sony cares about its customers as seen during the conference when they announced that there was no DRM, they support used games, doesn't require 24 hour check in, and doesn't need to be connected online. Let's also not forget about what happened when the 360 came out with the Red Ring of Death. I had to get it sent in 3 times, til I finally decided to switch to a PS3 and I haven't had one problem since I bought it. Sony's hardware is better, they care about the consumer, and they've constantly had great games
