I never sell my consoles.

When PS4 runs PS3 games

Hint: never

Nevar.

Probably never, unless PSNow is cheap and functional and lets me play all PS3 games I want to. I have owned one since 2008 and there are still tons of great games I have not played yet too...Lords of Shadow 2, Yaiba Ninja Gaiden Z, and Persona 5 aren't even out yet.  Also it is going to take at least a year or more I would think for me to start having a PS4 backlog...Won't sell 360 either as I don't want to have to rebuy Trials and Halo.

Never! Im not fool

Never. The PS3 still has a lot to offer.

Got my PS3 and WiiU/3DS - I feel complete as a gamer! No PS4 rush for me (if at all).

Err... never? The PS4 isnt backwards compatible. Where would i play MGS4, Uncharted 3, Fallout new vegas, Tales of Xillia 2, Tales of Zestiria, God of war ascencion, Persona 5, etc. when i feel like replaying them?

The only console i ever sold was the original Xbox, cause the 360 had a sort of backwards compatibility for my games.

never. im not making the same mistake I did with PS2.
Plus, ive got a ton of great games I still havent played yet, or started but never got around to finishing...and they go back as far as MGS4.

fixed it for you, even though I'm still not quite following Sony explaining this service.
