Much like their disc-based counterparts, PlayStation 3 downloadable games won’t be supported on PlayStation 4. What that means is your entire PlayStation Network library is going to have to stay put, and won’t be carried over to the next generation as many people were hoping it would. That’s no surprise considering the major changes to the system’s architecture which, other than the issue of backwards compatibility, are excellent news. This leaves gamers who wanted the PS4 to fully replace the PS3 currently sitting on their entertainment centers in an unfortunate position, although it does present Sony with an opportunity.
Backwards compatibility has never been a guarantee going into a new generation. More often than not, it’s been something we’ve had to do without: NES games didn’t work on SNES, SNES games didn’t work on N64, N64 games didn’t work on GameCube, Genesis games didn’t work on Saturn, and so on. More recently we’ve had exceptions to that as the media games were delivered on became more consistent across generations with CDs and DVDs. The current generation of consoles initially promised backwards compatibility to varying degrees, but eventually Sony stopped including the hardware necessary to play PS2 games on PS3, Microsoft stopped adding Xbox games to the list of those that could be played on 360, and Nintendo left GameCube support out of the most recent Wii hardware revision. Now, with not even PSN games being playable on PS4, you can see that there is more to backwards compatibility than having a way of getting the data onto the newer system — particularly when the system they were originally on had complex hardware.
