It looks like they are using elements skipped over in the first part of season 3 from the graphic novel since Tyreese shows up much later in the TV series, while combining it with what has been going on in the graphic novel after the prison. Interestingly enough, there is no sign of the Governor... I expect him to show up at the mid season finale after this mystery killer is found out, and conclude the season with a final resolution. Now that I see how close they are to passing the graphic novel. I understand why they've kept the Governor around. If they proceeded, they'd only have about 2 more seasons of source material.
Anyways... I CANT WAIT!!!!!!!!!!!

It appears that the PS4 will try to emulate Steam's success in digital game management by tying your digital games to your specific account. With the games tied to your account you will be able to access your digital games on any PS4 you log into. This is very different compared to how the PS3 handles digital games. Currently the PS3 will allow you to have up to two PS3 consoles active for your digital games. Which means if you own two PS3 consoles you can log into each of those consoles and download any of your digital game purchases.
However, it is possible to log into any PS3 system and still access your digital games. By having 1 primary console for your account at your home, you can easily go to a friend's house, use their PS3, log into your PSN account and download your games and start playing. That system would then be considered the second active system for your digital game purchases. Of course, once you finish playing at your friend's house you must remember to not only log off, but also to deactivate your PSN account off their console (PlayStation Support). This is burdensome and many people do not know that they have to do that extra step. The PS4 simplifies this and allows you to log in to any PS4 to play your games. This is where the next major difference between the two systems take place.
On a PS3 you can purchase a digital game, download it and all users on that console have access to that game. If the PS4 will have all digital games tied to a specific account, then all users on any console could very well be locked out from having access to playing these games. If all you have for your game systems is a single user account, then this is not an issue. But if you have a family with multiple user accounts for everyone in the house, then this could become a large issue if the only way to play a digital game is to be logged in as the account that owns it.
Hopefully the PS4 will have a family sharing option that allows all users on a specific console to play games purchased, because if not, physical game discs will have another advantage over digital.
