I would have expected one between Oslo and Göteborg. But that will probably come later.
I have to say though that the US-network has absolute priority over anything in Europe. Most US drivers (outside of California and the Northeast) have been waiting for months (up to a year) for a supercharger in their area. And there are already 10,000+ cars on the road. So rolling out that network should be first, second and third priority. Ofcourse it would be great if the European supercharger-rollout would be done simultaneously, but I don't know if it's realistic to expect that. Let's hope though that the extra funding makes that a possibility.
With 20 supercharger-locations across Germany, France and Italy the needs for most pan-European travels (business and vacation) from those three countries and from Norway, Sweden, Danmark, The Netherlands, Belgium, Switzerland, Austria and the Czech Republic would already be covered. Those 20 stations would probably already cover 95% of all European Model S-drivers' long distance needs. With another 30 stations for intra-country travelling - like the four in Norway - there would not be much left for desire.
