Approximately when? in the next 3 - 18 months
You can save yourself the trouble of asking Digitec. The answer is not worth the paper it is written on.
Pi 4s are currently sold out in Switzerland in all variants. You can't get any in Germany either. Amazon is also empty, apart from a few offers >200.- If you do find something that is acceptable in price, you shouldn't think twice.
If you really need/want one, I can only advise you to not only hope for Digitec, but also to observe other shops. Especially shops and price portals where you can be notified automatically when a product is available or at a certain price and then buy it quickly.
