Sony says that as things stand now, backward compatibility is not built into the PS4. Gamers will not be able to play legacy games on the new system, which may impact some of this year’s bigger releases like the Tomb Raider reboot. They say they’re working on it. They may be setting up to sell multiple forms of the PS4, some that will include backward compatibility for a price, and some that don’t. Backward compatibility can be gotten around via streaming games, but that requires hefty bandwidth that most American households still don’t have, or via downloads, which will take up valuable hard drive space and may create other issues. We’ll see. But the failure to provide backward compatibility from the get-go is an ominous sign that Sony may be looking to roll out their new box at one stated price, which is not the actual price gamers will end up paying if they want to keep playing their old Call of Duty titles on their shiny new systems.

I agree with him, but, sadly, backwards compatibility appears to be on the way out. According to Mark Deering of Gadget Insiders, the Microsoft 720 won’t be backwards compatible, either. It appears only Nintendo will allow its customers to play older games.

But it makes me wonder if Microsoft or Sony were ever interested in it at all.

Speaking from experience:  Microsoft only offered some backwards compatibility with its 360. And those games they said that worked often didn’t. So I gave up playing them on my system.
