I was not being sarcastic, but not really serious either about it being comparable.
I wanted to shake up a discussion about what each company can do to keep up with the other. TV is a biggie because it's not just a software or an additional service like Netflix, it requires the hardware to support it's integration.
If MS strategy works in getting more console sales with Interactive TV features, Sony will want to react. They both always look at each other and try to have everything the other have. Kinect and PSMove have successfully countered Nintendo's novelty, at least enough to stop losing sales to Nintendo. The 360 had an add-on HDDVD drive to mitigated Sony's bluray advantage (for a while). So I'm wondering if Sony could start offering this DVR hardware add-on for PS4 and work hard on a software integration, now that they have a real OS. (This was completely impossible on the PS3, because there wasn't any memory available, hence the DVR adapter being badly integrated). It sure won't be up to par with MS if only because it wasn't part of their focus, but I wonder if it could be enough to mitigate sales loss to the competition.
I think the near parity in sales between PS3, 360 and Wii, is not a coincidence or luck. It's because the companies worked they asses off to compete on every features and every market segment. We had the best competitive market this generation, and to a certain extent all three succeeded. I hope it will happen again next gen (but WiiU is already almost hopeless).
