Blue93I know this answer isn't really helpful, but: We will know in less than 24 hours. As those are somehow new Kailh switches in a new housing with light pipe little info is known, but I guess the most common switch types are available: linear, tactile, tactile+click and one special custom switch build by @HaaTa 's specs.
Blue93I don't think there's a linear option, but there are Kaihl Blue and Brown options, along with Haata's new switch, which might be a second tactile option. Hoping it's a good option. :)
