Speaking for myself, I liked what I heard today by-and-large. The idea of using the XBOX for an all-in-one entertainment hub is appealing to me.
Kinect is a novelty for me right now, but given that it is now an expected hardware component of every system I look forward to seeing what game developers can do with it to augment controller-based games. The idea of multitasking from a console, while not new by any means to PC users, is appealing to me as well.
The software library will affect whether I purchase an XBOX One on day one (particularly the sports titles, I want to see more than an EA Sports trailer which was quite obviously CGI, and I want to know what Forza 5 has besides jaw-dropping graphics), but so far, so good.
