Mode Designs has announced on their official Discord that pre-orders for the “Prologue,” a 98% keyboard currently in development, will begin on Thursday, September 17, 2026, at 1:00 AM JST.
While Greenkeys has been providing continuous coverage of the Prologue since the teaser was released in February 2026, this marks the first time a specific pre-order date and time have been officially announced.

No New Product Specifications Released at This Time
The primary focus of this announcement was the specific start date and time for Prologue pre-orders.
Mode Designs has indicated that they will be releasing more detailed information over the coming weeks.

- Pre-order end date and time
- Estimated shipping schedule
The official Prologue page currently only lists the 98% layout and the product concept, with a sign-up form to receive further updates via email.
Continuous Coverage by Greenkeys Since the Teaser Stage
Since the teaser video was released in February 2026, Greenkeys has highlighted the possibility that the Prologue would feature a 98% layout with an integrated numpad.
The layout was later officially confirmed when Mode Designs explicitly labeled it as a “98% Layout.”
Furthermore, a development update in the summer of 2026 revealed that for the new Crown Mounting System, an 8-point support structure was chosen over a 10-point one to achieve the best balance between typing sound and support feel.
Pricing and Configurations Expected in the Coming Weeks

Pre-orders are set to begin on Thursday, September 17, 2026, at 1:00 AM JST.
However, essential information for making a purchase decision—such as pricing, kit configurations, color options, and shipping dates—has not yet been disclosed.
Mode Designs plans to release additional information over the next few weeks, and notifications will be available through the mailing list on their official page and via Discord events.
Let’s wait for further information.
