I am more sad at all the potential advances that have been lost / delayed:

    These changes will impact some of the scenarios we previously
    announced for Xbox One. The sharing of games will work as it does today,
    you will simply share the disc. Downloaded titles cannot be shared
    or resold. Also, similar to today, playing disc based games will
    require that the disc be in the tray

The last thing that next-gen consoles need is to remain anchored to last-gen practices. The road was going to be bumpy but, as many have said before, so was Steam and now everyone loves what it's become.
