I thought the format was effectively four groups of nine teams playing each other once (hence the 8 games, rather than the 6 it is now), and this was drawn up beforehand, meaning you WOULD know what eight teams you would be facing? Maybe I've misunderstood though.
EDIT - Actually, scratch that, just reading up on it just now, and you're right, there should be no way that's predetermined beforehand.
2nd EDIT - Now another source says the teams will be drawn beforehand, unlike the traditional Swiss Chess method. Who knows what to believe? Why couldn't they have just left it as is?
