Rainbow Six Siege Y11S4 Reveal Set for Nov 14 at 9:30 PM ET

Ubisoft will officially reveal Year 11 Season 4 of Tom Clancy's Rainbow Six Siege in a panel on Saturday, November 14, 2026, at 9:30 p.m. ET, according to a Steam announcement published on Monday, November 9. The panel will be broadcast on Twitch during the Osaka Major grand final.

In the post, titled "Year 11 Season 4 Reveal Incoming," the Rainbow Six Siege team says players can "hear directly from the development team" and get "an early look at the future of Rainbow Six Siege."

Panel schedule in three time zones

The announcement lists the Year 11 Season 4 reveal panel as November 14 at 9:30 p.m. ET and 11:30 p.m. BRT, which is 3:30 a.m. CET on November 15. The post does not give a start time for the grand final itself, a length for the panel, or a Twitch channel name beyond a "Watch on Twitch" link.

The Osaka Major is the current Rainbow Six esports event. A separate Steam announcement says it runs from November 6 to November 15 and that the best teams are competing for qualification points on the road to the Six Invitational.

What the post does not reveal

The announcement mentions "new gameplay updates, competitive improvements, and fresh opportunities" in the upcoming season, but it names no operator, map, mode, season title or release date. Ubisoft has not said when Year 11 Season 4 will go live.

Players can already see one direction for the season in Ubisoft's latest Community Checkpoint recap on Steam, which says that starting next season there will be no seasonal Ranked map pool rotations. Each Ranked season will instead have a pool of approximately 15 maps, including the nine maps currently played in Pro competition. The same recap describes Year 11 as heading towards its final season.

Ubisoft has not confirmed anything else about the season. Zero1Gaming will update this article when the panel airs. For more on the franchise, see our coverage of Rainbow Six Mobile's shutdown in January 2027.
