The original poster of the screenshot now says the image is a fake:
I DIDN’T LEAK NOTHING
by the way i have deleted the post on Reddit not Sony because it’s a fake
p.s Sorry for my Bad Bad Bad English
First posted on Reddit, then noticed by members on NeoGAF with the caveat that it could be a fake, a user uploaded a PlayStation 4 screenshot that appears to show the PlayStation 2 game Siren being livestreamed on PS4.
Before deleting it, the original poster said, “When I try to watch [the stream] it gives me ‘there are no content items,’ maybe because they are testing this feature.”
Assuming this screenshot is legitimate, it could mean Sony is testing out livestreaming ahead of a reveal that could be adding PS2 games/Classics to the PS4’s PlayStation Store, or perhaps adding them to PlayStation Now.
We’ve contacted Sony and will let you know if we hear anything back.
