The answers run the gamut from graphical improvements to Kinect control features to online services and more. Sure, some of the answers veer into the kind of pat, focus-grouped PR-speak that game company representatives are fond of throwing around at events like these. Still, these answers represent what developers see as the best reasons currently available for a gamer to upgrade to an Xbox One at launch. Hopefully, they will help clarify whether an upgrade is worth it for you.

I think having Kinect everywhere is the main feature that truly differentiates [the Xbox One]. The Xbox Live integration is cool, but it's not something that wasn't there before, and the graphics resolution is higher, but it's always higher. I think doing something with Kinect that you can't do anywhere else is a huge thing. All of us developers are figuring out "how do you really emotionally connect with people?" and I think you saw the reflection of the face [in a monkey that imitates your facial expression]. I think there's something there; I think it's the beginning of something...

I think [having the Kinect] is important in that you can go a little bit farther than you could go otherwise. I think voice is extra convenient, honestly. It's what I do—I lean back and just give my commands and it does everything. The gesture stuff—we did a bunch of Kinect games where we did gesture stuff, for example Kinectimals, and I get e-mails from people with two-year-old daughters... and Kinect couldn't pick up everybody. So that's why we did both. When you want to, you can use [gestures], but you don't have to. I think that's a better approach
