When Sony patented a means of linking games to systems so that they couldn't be sold again, people positively flipped. They feared that the "PS4" would implement it. They feared that "PS4" would be absolutely doomed using such a practice. I suggest to them, however, that they partake of a chill pill.
The first point is implementation itself; will it be used to stop the used? Well, has every one of the Big Three's thousands upon thousands of patents been put to use? Hardly. Have you played with the Wiimote Football ( http://nintendookie.files.w... )? Have you tasted the joys of Sony's tongue controller ( http://www.playstationlifes... )? Is Microsoft's game helmet all the rage ( http://www.eteknix.com/wp-c... )?
No, no, and no. Sony, Microsoft, Nintendo....they are corporations. Their first priority is OWN ideas, not implement them. They want to be the first ones to get everything on paper so that they can license them if someone else wants to use it or have it ready to use for themselves. Even a tongue controller could have abstract researching purposes.
Beyond the question of "will they use it?", many think that if they do, it would mean instant doom for the PS4. I think that is absolutely comical. I hate the idea, but here's the thing.....I hate DRM, online passes, constant breaking down of content into DLC, etc....but that's EXACTLY what people put up with. Most PC gamers primarily use Steam, a service that essentially acts as DRM itself. Sure, you can trade SOME items/games, but those games still lose any REAL monetary value once you purchase them. On the console front, there's so many passes and codes that I feel like I'm going through the TSA before boarding a plane.
We sign away our souls and own nothing as we accept TOS for games, songs, movies, etc. PS4 wouldn't be doomed for locking games to systems. It wouldn't be much different from the way things are done today in many ways.
I'm not worried. Sony considered it for the PS3 and it didn't happen then. They had the "audacity" to patent such an idea and the internet is ready to lynch someone. It's incredibly unlikely that they will actually do such a thing.
Rest easy, internet. Unless Sony actually uses the patent, there's zero reason for such panic.
