At least the grey one is listed as available when I checked on amazon.de.
All versions are in stock at mediamarkt.de. The console is sold out every now and then, but you don't have too much problems getting a switch here in germany. Just order it and it should arrive in 7 to 14 days even if it is listed as not available I'd say.
It's really not too bad. Me trying to get a RTX 3080 for a somewhat reasonable price, that is a whole different story and I'm starting to wonder if I will even get such a card sometime this year...
