I have to admit I know nothing about Swiss football, Diomed, but I always prefer to avoid (or even oppose) teams moving to a new ground. The fact it's a new ground takes away a large part of the home advantage, the feeling of familiarity with where they're playing. The away side will be just as (un)familiar with the ground as the home team is. Obviously it would be disappointing for Baulmes if they don't win, but that doesn't mean it won't happen. Look at Arsenal in their new ground this season, their first two games at home ended in disappointing draws against Aston Villa and Middlesborough.
The fact that it's a local derby would also put me off - anything can happen in those kind of games, and I'm sure their opponents would love to make their rival's first game in their new ground a miserable one.
Good luck if you go with them though
