It seems to me that Comcast is getting ready to match Apple's alleged new AppleTV and associated streaming service.
At this point, everyone is able to stream some semblance of their video content on their own wifi network. The point is that it requires contractual changes to go outside of wifi (companies like Comcast and DirecTV already do this for certain channels).
So, while on the face of it Comcast looks like they're doing a whole lot of nothing, remember that their video subscription base is in free-fall while their Internet services is growing. In the short term, this move allows Comcast to advertise more flexibility with their service (though for those of us who know the technicals, this is a great, big "meh"). In the long term, they may be setting up for competitive advantage.
