Besides guessing the medals, I think it's also interesting to guess the regional champions.

My bets are:

European champion: SPbSU Asian champion: Tsinghua U North American Champion: Waterloo South Pacific Champion: University of New South Wales Latin American Champion: Universidad Nacional de Córdoba Africa and Middle East Champion: Faculty of Computer and Information Sciences, Ain Shams University

And I'm also guessing that I wrote them according to their relative order in the scoreboard.
