My predictions:

Lions-Blues: Blues to thump the Lions as they have these past few years
Force-Hurricanes:Hurricanes
Reds-Highlanders:Highlanders
Stormers-Brumbies:Brumbies
Bulls:Waratahs:Holding thumbs for the Bulls
Sharks:Cheetahs. Daaaaah-dum Daaaah-dum dadadaaaaadum
Cheetahs never prosper. Nor do they swim too well.
