In the last national tourney there were 7 teams participating and still a few forfeit losses occured. (Yes, that was just half a year ago, and even getting 8 3v3 teams wasn't possible.) Sven is way too optimistic about the amount of teams. The countries that participated last time would most likely be in. If you add Sweden, Belgium and Croatia/Slovenia to them, there could be 10 teams at most.
And if that's allowed, I'd like to play for Germany. I've been living here for a few months already, and planning to stay here for at least a few years.
