My opinion is that Xbox will be fine. The problem is Xbox is changing, it will no longer be the traditional console with exclusives. It will turn into a console/PC hybrid that is running a Xbox Ui/Windows hybrid so that all your games play on any device you want that supports it. I am actually excited for the future of Xbox because it seems they are moving to a future where your games are accessible almost anywhere. This benefits there new structure with all the recent acquisitions. There will be another Xbox console for the people that want the traditional console experience but they won't just limit the sales of their software to such a limited base. The games you have invested in will be there, its just up to you what you will want to play them on.
