Microsoft has confirmed that it will "share updates on the Xbox business" this Thursday, the 15th February, at 12PM PT / 3PM ET / 8PM GMT / 9PM CET. In other words, this is when the beans will finally be spilled on Xbox's all-but-official multiplatform plans. The news will be delivered through the Official Xbox Podcast — which immediately raises questions about the potential scope of these "updates".
In any case, this could be big for us PlayStation fans, and we'll be covering the news from a PlayStation perspective once it breaks. While we're sure Phil Spencer and the gang will tiptoe around the specifics, it'll be interesting to see how all of this goes down.
