As was whispers' wont this week, yet another rumor centering on Sony's PS4 surfaced late Friday.
This one comes by way of the Wall Street Journal, which reported that Sony plans to utilize Gaikai, a game streaming company Sony owns, to stream existing PS3 games to the new console.
Why not new games? Those will apparently come on an optical disc.
Sony has allowed for backwards compatibility before with its older consoles - gamers could pop a game disc from a PS1 game into a PS2 console, PS2 games could run on a PS3 - but the new ARM x86 chips reportedly housed within the new PlayStation won't allow for the cross-generational play.
Gaikai is a cloud-streaming service that streams video games over the web, much in the same way as movies and music are accessible, according to the company's website. Sony bought the company in July 2012.
If Sony plans to host pre-PS4 games in servers and send those down to the new consoles, it's sure to keep its backward compatibility streak going.
The Verge noted that services like Gaikai and OnLive have delivered games at a max resolution of 720p, possibly preventing the former from sending new PS4 games to the console.
It might even be a stretch for Gaikai to deliver PS3 titles as it hasn't been used publicly to stream anything but PC games, however Sony has likely poured plenty of resources into addressing the issue.
If Gaikai's services are intended for use in the new console, there's virtually no limit to where games could go. Think PS Vita, PS3 and potentially tablets and phones.
