This is a question for the future. I do not expect a knee-jerk reaction over Sony's relatively open stance on things Microsoft is clamping down on. I also think that Microsoft's offering of a "multimedia box" could be just enough to wrangle TV watchers and balance out their user-base.
HOWEVER. Let's imagine that the general populace is just as put-off as the loud minority about these draconian restrictions (cool word, huh?). Let's imagine that 2 years into this cycle, PS4 is outselling XBONE 5-to-1, if not more so. Would Microsoft be willing to lose face (and control) over their ecosystem to get back into the game, or will they maintain course despite poor sales and consumer hostility?
Personally, it's a hard call. In the short term, they may back off a bit, but I do believe we are moving towards a digital future. Although Microsoft is getting on the band-wagon early, maybe in 5 years this will be the standard for most consumer devices / services. Someone somewhere mentioned that they included an ethernet port in the 360 years before broadband was mainstream, which shows forward thinking on their behalf (for the benefit of the consumer in this case, but that's irrelevant).
