How long is Rocket League off-season? Judging by past off-seasons, the break between Seasons 14 and 15 should only be a matter of hours.
Rocket League's Competitive Season 15 is coming soon, likely next month. Season 14 began on Mar. 25, and seasons typically don't run longer than four months.

Season 15 and the launch of free to play are likely both be part of the same major update, and the off-season will take place right before it.
