The game isn't in Xbox Live certification yet.
I do love the period just before a major industry expo. In news terms, and to quote Gandalf, it's the deep breath before the plunge. A less glamorous way of putting that is that there's sweet Fanny Adams to report on right now, save for the scrapings of the internet's barrel. For instance: did you know that Minecraft still isn't on Xbox One yet? Well, now you do.
