Wow, if you guys read on article on used Games, DRM, and industry woes; gotta be this one:
Wow is right, that article is brutally on point.
My guess is PSN will be providing servers or some sort of matchmaking service which game developers can make use of if they want, and this will of course be behind the paywall. For F2P games, they want to lower the cost of entry and encourage as many players as possible, so they won't be requiring PS+.
The problem is not that MS is not trying new things. In fact Kinect is incredible technology and deserves to get more recognition and use in other areas besides games. The world is also slowly moving towards digital distribution and MS is building for the future.
The problem is consoles have always meant something very different than PC. PC gamers are used to all the benefits of Steam etc. Consoles are used by many people as their main source of entertainment, esp in low income families, many countries outside the West etc. Cutting out used games, requiring not just online but broadband, removing the concept of ownership, is fundamentally changing what it means to own a games console.
Then they try to dress it up as a media device (which only works in US for TV), when in fact every other console, Roku, bluray player has the same streaming services (but free), and price it out of reach of the casual gaming market.
