fusion makes sense as a name because I heard the new console is going to come in two parts that can be used independently of each other. The 'on-line' only one is set to compete with AppleTV or Steams Big Picture and then something else(not sure what the other half consists of) also heard a rumour that they will also still work with the current xbox.
I do think the name is a bit too 90's though it still makes sense.
