The Remote Play functionality is going to come to both Windows PCs and Mac computers, and gamers will be able to play PS4 games they already own on those systems by streaming the games from their console.
The news wasn't published in a press release. Instead, The Next Web reports that Sony's president of worldwide studios sent a tweet confirming that the company was working on releasing a desktop version of Remote Play:
Some people asked if we plan to provide Remote Play function to PC, and yes, we are indeed working on an official application for PC/Mac. :D

Sony recently announced plans to introduce support for PlayStation 2 emulation on the PlayStation 4 console. That would allow gamers to play old games on the newer console, possibly by downloading them from an online store.
