Why do I feel the urge to buy a PS4?

[*Sound Of Rain]

I've never had the urge to buy a PS system before. I've owned all 3 previous consoles but that was because of family members and gifts. I've enjoyed all of them but have never bought one myself...now I feel the need to buy a PS4. Yet, none of the games interest me besides for InFamous SS. 

I think I mainly want to play some PS classics but my PS3 broke. Does PS4 have PS classics yet? 

Anyway, I always planned to buy a Wii U first (got it earlier this year) and then depending on E3 get a PS4 or XBO during this Holiday. Now, despite the XBO having Kinect (which I like) and better exclusives for my tastes so far, I want a PS4. 

Thoughts?
