According to Euorgamer, sources within camp Sony have suggested PS1, PS2 & PSP games could be on there way to the PS4 via a firmware update. Sony recently announced that a cloud streaming service, known as Playstation Now, would be coming to the PS4. This service would allow subscribers to stream online the entire Playstation 3 back catalogue. Whilst this service has potentially been applauded by fans, many suspect the application to run into a few technical issues, especially as Playstation Now will rely heavily on the populations download speeds.
However, Sony may opt for a more conventional means of backwards compatibility when it comes to it’s PS1, PS2 & PSP back catalogue. A codebase is currently in place on the PS3 to enable these older formats to run. However, with the immense power of the PS4, these classic games could potentially run flawlessly. In theory, these games could all come out looking like HD re-releases. If Eurogamer’s source is right, Sony have in place, thanks to the PS4 set up, a means to emulate older titles that will run free of the poor and blurred upscaling. This coding could mean Sony will have to do little to patch their titles (if at all), making the Playstation Store a heavily stocked market place.
Whether PS3 games remain on the upcoming Playstation Now service or move to the PSN store as well remains to be seen.
