Because they are jealous of the nice weather and good food in Ticino.
More seriously, all the languages are included in the game. I bought the German version, inserted the card in my switch and the game started in French... So there you go.
As mentioned:
Language: German, English, French, Italian
Language of subtitles: German, French, Italian, English
Language of manual: French, German, Italian
Furthermore, prices are based on supply and demand, suppliers and availability of goods. For all these reasons, there can be a price difference between the same product in different languages.
Without really having any further information at the moment, I assume that they are only available digitally. However, if they are released in a physical form, we can certainly offer them ;).
If it was sold out, you couldn't put it in the shopping cart anymore ;) And the game won't sell out that quickly. You can still buy Twilight Princess HD for the Wii U today.
