Sony obviously ditched the eye near the last minute, otherwise they wouldn't have invested so much tech into the controller to work with the PSeye. I wish Sony would have showed 2 SKU's as was hinted earlier (that they would have 3).
There was talk about MS doing some Live subsidy, I think Playstation might be in the best spot currently to do it. Offer the PS4 with PSeye for 399 with 2 year subscription of PS+. In essence they would pay the same as Xbox-One (without Live fees) and it might help get more Eye hardware out there.
I'm surprised people are not bringing up the huge impact the difference between Sony and MS DRM policies. It is HUGE not just because of what that means for consumers..but exposure. Think about it for a second. If someone who knew nothing about these two systems went into a Gamestop and saw 2x the PS4 content compared to the Xbox One it's going to make them ask "Why"? Second if someone takes a stroll through the local video rental store Xbox - One will not exist; it will literally not exist. They will see, Wii, WiiU, PS3, 360, PS4.
Other gaming industries will also look lopsided, Goozex and Gamefly for instance will not have Xbox One content (at least 100% for Gamefly) Say what you will about the DRM limitations for individual consumers but the exposure (or lack thereof) for XB-One content is going to be extremely negative.
People are moving towards digital downloads. This issue is overblown.
