Cue all the DRM haters: there's a nasty little rumor floating around that Sony is considering implementing serial keys and requiring activation of games and Blu-ray movies. While it's all speculation at this point, it's quite a blow for those of us that like to trade games with friends or even sell used copies.

The recent unveiling of a root-key hack that completely shuts down PS3 security measures could be the reasoning behind Sony considering such actions on future releases. According to a "very reliable source" at the Dutch site PS3-Sense, the new serial key process would pair software with specific Playstation 3 consoles and authenticate them with Sony's servers. Games and such would be able to be activated on up to five different machines before becoming useless. This would not only put a huge dent in the resale of used games, but could also make having an offline PS3 almost impossible. Here's hoping the rumor mill churns this one into a deep hole where it belongs.
