With Google's investment in the Zurich office, and the much, much more internationally competitive wages you can earn in Switzerland, I think Zurich could be better positioned.
There's certainly no reason to believe that specifically an EU city would be the next to take off. And in most other ways, the Swiss job market is just much more competitive.
I'm also depressed by the article using a picture of an anti-human violently wide open co-working space as a stereotype of a thriving start-up culture. Nothing says you're being totally taken advantage of like a wide open floor plan.
