Silksong at One Year: Where Sea of Sorrow, the Physical Editions and Hollow Knight Stand

Hollow Knight: Silksong launched on September 4, 2025, and a year later the question on everyone’s lips is the same one it was in the spring: when does Sea of Sorrow arrive?

Sea of Sorrow: what is confirmed. Team Cherry announced the expansion in its holiday 2025 blog post, describing it this way: “New areas, bosses, tools, and more! Hornet’s adventures continue in our nautically themed expansion, coming free for all players next year.” The studio said to expect additional information shortly before launch. In the material we retrieved, no release date has been given, only the 2026 window.

The worry. On September 9, OpenCritic ran a piece noting that some fans are beginning to fear the expansion could slip out of 2026. To be clear, that is fan speculation. The same piece notes that Team Cherry said it would talk about the DLC closer to release, and it quotes no new statement from the studio about a delay. Treat any “it’s delayed” talk as rumor until Team Cherry says otherwise.

Physical editions land October 16. According to Screen Rant’s report from May 28, physical editions of Silksong arrive October 16, 2026, for PS5, Xbox One, Xbox Series X|S and Nintendo Switch 2, distributed by Fangamer. Listed prices are $39.99 for PS5 and Xbox and $44.99 for Switch 2, with a 32-page manual and a Pharloom map in the box. The original Hollow Knight also gets a physical re-release the same day on PS5 ($34.99) and Switch 2 ($39.99), with a Hallownest map.

The original gets a refresh too. In that same holiday post, Team Cherry said it is building a Nintendo Switch 2 Edition of the original Hollow Knight with higher frame rates, higher resolutions and enhanced graphical effects. Existing Switch owners get it free in 2026. Updates for all current versions of the original game, including support for 16:10 and 21:9 aspect ratios, were already available to PC players on Steam and GOG public beta branches at the time.

Reception, for the record. Screen Rant’s May report put Silksong’s OpenCritic score at 91 out of 100 and noted that the game “broke Steam and every other digital storefront on launch.”

Bottom line. A year in, Silksong is a shipped, acclaimed game with a free expansion promised for the back half of the year and a busy October for collectors. Whether Sea of Sorrow makes 2026 is a question only Team Cherry can answer, and it has not yet.
