I thought the review/preview of the XBOX One hardware was supposed to come out today? I know IGN said they would have it and so did Revision3, but it's certainly a tad bit late already.
IGN did have an article up with a summarized version of an interview with a guy about the controller and what changed. In regard to that article, I was a bit disappointed with his thoughts on the d-pad. He pretty much said that all games use them differently, which is true, so they don't want to specialize it for one particular type of game. In my experience, the issue with fighters is a lack of precision in reporting the directions pressed. People playing Call of Duty and using the d-pad for the various commands are just pressing the basic directions. They shouldn't be hampered by increased precision.
