This is a burning question. Will the Last of Us be available for the PS4? or a better question, will the PS4 be backwards compatible? and if that Back wards Compatibility is limited will the Last of Us be one of the few games included?

You won't be able to play your PS3 disc games on PS4 but they want to fill the online library with every PS game ever. I'm hoping there'll be a code system of sorts to be able to play the games you already own on disc once the cloud library is up and running.
Once Gakai is up and running, any game that devs have worked on to support the PS4 framework will be available there.
Its unsure at the moment if games purchased on the PS3 will be free once Gakai is opened.
The PlayStation 4 isn't going to be backwards compatible natively at least. You have to wait until Gaikai releases their cloud services for the PlayStation 4. Then you will be able to play this game on the system. But I believe they said it won't be available until sometime in 2014.
I'm getting both consoles. The PS4 for it's exclusives and awesomeness and the Xbox One for it's exclusives and awesomeness.
