I'd go for a PlayStation 4. I think it has better exclusives than the Xbox One. Xbox isn't a terrible system, but I don't like the way the Kinect will be watching you. That just seems like an invasion of privacy. Also, I don't know if that 24 hour check in thing has been removed or not, but that's just stupid. PS4 will also be cheaper, at least the system will. Plus, there are many exclusives- Ratchet & Clank, Sly Cooper, God of War, Infamous, Uncharted, Killzone, and more. I can't really include Jak & Daxter since there hasn't been a new one for PS3 at all, not including Jak HD Collection since it's just a remake of the PS2 titles. So, I'd just go for the PS4 if I were you. That's just my opinion. I am going to wait a couple of months before buying one just so I know if it has any problems.
I've enjoyed PlayStation and Nintendo for years, but I can agree that the Wii U isn't much to brag about.
