There has been a lot of talk about new Xbox hardware recently. Phil Spencer talked about the idea of an iterative console a few months back, but has walked that back a little recently. There has also been talk about a slim version of the console possibly coming circulating online.
Interestingly, there is more to this as well. This listing turned up on NeoGAF yesterday which hints at something called the Xbox One II which has been in production since February. That is around the time Spencer made his first comments about an iterative console.
Lots to think about here, but I suppose the most important is, is this just a slim version of the Xbox One, or perhaps something closer to the PlayStation Neo? That seems to be the million dollar question.
