Update:

Psyonix addressed the PEGI rating and said a PS3 version of Rocket League isn’t happening:

For those asking, Rocket League isn’t coming to PS3. That PEGI rating is legacy from our initial PEGI rating submissions… (cont.) — Rocket League (@RocketLeague) November 18, 2015

We ended up not having resources/time to do both PS4 & PS3, so PS3 version never happened. Not sure how/ why the legacy rating was published — Rocket League (@RocketLeague) November 18, 2015

Original Story:

After developer Psyonix announced back in August that Rocket League is “absolutely, 100% going to other platforms,” it looks like a PlayStation 3 release could be right around the corner.

Thanks to a new rating from PEGI (Pan European Game Information), it appears as though Rocket League PS3 will soon be a reality:

Psyonix has yet to confirm a PS3 release of Rocket League, so we’ll have to wait for official confirmation.

What we do know is that Rocket League isn’t planned for PlayStation Vita, and the developer has lots of new content in the works for the PlayStation 4 and PC versions.

Would you play Rocket League if it came to PS3?
