Screenshot is from the latest episode of YuruYuri San Hai directed by Hiroyuki Hata. Yes, no PlayStation, PlayStation 2, PlayStation 3, or PlayStation 4. This probably doesn't actually mean anything BUT...
Someone from the Internet found the following tweets made by Hata sometimes ago:
(I try to translate as accurate as possible)
Tweet 1
-"PS4 using the BD media again. It looks like it's gonna be difficult grilling the meat."
Tweet 2
-"Well you see, I haven't switch on the PS3 for a while, so I start it up, updated to the latest firmware version, and the whole screen blackout after the reboot. I checked the official support on how to deal with it, tried to boot the PS3 into safe mode and nothing happened \(^o^)/"
Tweet 3
-"I never trusted s◯ny products from the beginning, I should've think further."
What do GAF think?
