It might be a matter of taste/preferences, but neither system of the new generation has enough games to warrant a purchase for me at this time.
To be fair, WiiU has the most, followed by the Xbox One. PS4 literally has nothing that appeals to me; coupled with my horrible experience with Sony's online services and hardware reliability, and I am very resistant to picking up a PS4 until there is a full blown hack. If by some chance I do get one as part of a repeat of Gamestop's multi-console deal, I'd be locking mine up until there is a full blown jailbreak/mod for it.
