I think your thread title is a bit over-dramatic, as we don't know enough about Durango or Orbis yet. For example, cloud gaming could be considered to be a new hook. So could a multimedia hub with a DVR. They could be unique in their own way while traditional in others.
However, I will say this, which kind of mirrors your conclusion: If Microsoft and Sony take very similar approaches to each other again this time, it's certainly possible that the market will adopt one over the other, making that console compete for first place with WiiU and its unique approach... unless WiiU bombs, which is highly unlikely IMO.
