In an interview recently David said it was about 70 people. I think it was the E3 one. No, wait; the German one perhaps.

DB: There are several dimensions to it, I think. Put in today's language, Ian and I were a micro-studio, and when you're in that environment, communication is so much easier. The largest game that Frontier Developments has made to date involved almost 400 people! While the Elite: Dangerous team isn't quite that huge, between 70-100 people are closely involved.
