That figure is the Norwegian Microsoft Store pre-order price for the XBOX Nano Controller, not proof of a 100-gram body, a 50-euro price, or a November launch. The store page calls it "Our Smallest Controller" and invites pre-order, but the page does not list mass, battery, connectivity, or a release calendar.

Die Brief reads the number as a retail signal, not a spec sheet. A pre-order price in one currency constrains the buyer who wants a cheap second controller, but it does not constrain the fab, the latency budget, or the input stack. The document proves availability in the Microsoft Store, not performance.

What remains unmeasured is the physical and electrical side: weight, button travel, battery life, wireless protocol, and the actual ship date. The page leaves those blank, so the 100-gram and November claims stay outside the document.

The document does not state weight, euro price, or ship date.

The store price is a commercial data point, not a hardware specification. It bounds accessory cost, but it leaves latency, power, and input behavior unverified.
