The new US English backlit keyboard comes standard on Fedora pre-built Core 5 and Core 7 systems, and is an option on any DIY Edition. On the backlit keyboard, we’ve also switched to a reprogrammable keyboard controller using open source ZMK firmware. We’ll be moving to that controller and firmware on each language of non-backlit keyboard over time.
One of my biggest complaints about the Framework 12 was the non-backlit keyboard (which was not that big of a complaint, really), so it is nice to see them address that. It is neat that they made it ZMK, as well.
EDIT: I am not seeing the new keyboard on their marketplace. I assumed there would be a "preorder" available like they usually do, but they only have the 1st generation versions of the keyboard on the marketplace.
EDIT: Preorders are live now. Same price as generation 1. Interestingly, while the listing does mention a backlight in multiple places, it does have this paragraph:
Made of 30% post-consumer recycled plastic resin, the Input Cover Kit comes in a variety of layouts and languages. This kit includes a pre-assembled Keyboard and Touchpad. It features full-size keyboard with 19mm key spacing, 1.5mm key travel, and a non-backlit layout.
Note the "non-backlit layout" part at the end. I assume that paragraph is just a mistaken holdover from the 1st generation listing.
