All Model01 keyboards ship with US-QWERTY keycaps by default. There are additional keycap sets being produced (black painted blanks, translucent white blanks, Dvorak, Colemak and Linear A sets). I’m not sure if there are plans to offer localized keycaps anytime soon.
Mind you, you can reprogram the keyboard to support nearly any layout you can imagine, it just won’t fully match the labels (unless you use blanks).
