That was definitely interesting. I was almost positive that Sony was going to announce the PS4 was going to have the same disc policies. Microsoft had to have had some push from developers for them to implement the system that they did. Microsoft isn't making any money off of it, so it wouldn't make sense for them with all this community push back.
So a few thoughts from that. Microsoft got exclusive content for CoD and Battlefield 4. Those two games are the huge money makers in the game today, perhaps it was those two developers that pushed Microsoft towards this and in return they get that exclusive content.
Also, if other developers see that the Xbox would make them more money to develop for them because of these disc policies, you possibly could see a shift in a bunch of exclusive developer rights headed to the Xbox which could hurt the PS4 in the long run. Just a thought.
My real reaction to all of this is I think Microsoft back tracks on this DRM and their disc policies a bit. The kind of backlash they are receiving right now in the gaming community is the kind of stuff you see companies go under for. Specially in a business that is so driven by consumer loyalty. I think they get rid of the DRM, let people do whatever they want with the game they purchased but have some sort of activation fee in place for used games so the developers can get a piece of the pie. They could easily work with Gamestop to assign different priced authorization keys depending on how old the game is. Older games would be cheaper to activate. Everyone wins.
