Rocket League’s anticipated cross-platform RocketID feature has been delayed into 2019.

Developer and publisher Psyonix has been working to bring cross-platform play to the car-football title for a while now, first announcing plans in May 2017. The RocketID system was due to drop this year, but has been pushed into early 2019 to “ensure that it’s as intuitive, stable, and polished as possible.”

“While our goal was to release RocketID before the end of 2018, we’ve made the difficult decision to push its release into early 2019,” said Psyonix in an announcement this week.

“The good news is that with Sony’s recent announcements regarding full cross-platform functionality, we can now make additional changes to prepare RocketID for ALL platforms should we receive permission to do so!”

While Psyonix doesn’t explicitly mention the platform, it’s possible that more development time could bring the PS4 into the RocketID ecosystem. Sony finally made a cross-platform exception for Fortnite, after all.

The rest of the blog post lays out plans for the rest of the year, including a winter Frosty Fest 2018 event that will let players unlock themed cosmetics.

It’s been a strong year for the speedy sports title. Rocket League has attracted over 10 million new players since the start of this year.
