Rocket League has been rated for Xbox One by a Taiwanese video game rating board, suggesting the popular soccer-with-cars title will be launching on Microsoft's console soon.

The listing, which was spotted by Gematsu and Twitter user Lifelower, is the second recent indication that Rocket League's PlayStation exclusivity is coming to an end. In November, developer Psyonix said it may announce the game for additional platforms by the end of the year.

In an interview, studio director Dave Hagewood was asked if the game would ever come to Microsoft's Xbox One.

"[Laughs] I can't say," he replied. "We're looking at all kinds of platforms and there may be some announcements coming up at some point. Hopefully before the end of the year, but I can't confirm that."

This followed statements by marketing VP Jeremy Dunham, who confirmed in August that Rocket League is in the process of being ported to other systems.

"Yes, we are definitely bringing Rocket League to additional platforms," he said at the time. "We'll have an official announcement of what platforms those are (and when) a little further down the line."

Currently, Rocket League is only available on PC and PlayStation 4, where it launched as a free PlayStation Plus title as part of a partnership with Sony.
