South Africa hosts the European group? I hope not.
I don't think it will happen, because it's cheaper to fly one South African team to Europe than to fly three European teams to South Africa. My pick is Germany, because they hosted a round in the 2009 Baseball World Cup and had the best attendance per game in the tournament. Also they have expressed interest in hosting a round of the upcoming WBC Qualifiers. Then again who knows what the Steering Committee will do at this point.
