Pros:
In addition to Sony's policy of no DRM, no online requirements, no restrictions, and no authentication, the PlayStation 4 is also region-free and its HDD is removable and upgradable, which IGN thinks would give PS4 advantages over Xbox One, which is region-locked and has inaccessible HDD.
The system will feature downloadable content similar to what is available on other PlayStation platforms.
PlayStation 4 Supports Used Games.
The PS4 does not require an Internet connection to function.
The PS4 also features technology that attempts to determine trends, including titles a gamer is likely to express interest in next, and then automatically download a small percentage of those games in the background, even in sleep mode, in order to save time.
Games on the PlayStation 4 will not be region-locked.
Cons:
The PlayStation 4 will not initially include the ability to support previous PlayStation console games.
The PlayStation 4 looks like the Xbox One in italic. :/
