It'll likely appear when sufficient quantities are available to serve the reseller market -- but brand new models tend to be very limited in availability, so expect a wait before that happens.  
I know that the new XPS models is available through dell.com in Norway, but my company has partnered with atea.no, so I have to buy through there. Does anyone know when the model is available from other stores? it seems like no other online stores have them except dell.com
When is the dell xps 15 (2023) model coming to norway?
