The Sharks and the Waratahs currently lead the conference standings in South Africa and Australia, respectively, and, owing to the good form each has produced in recent weeks, are on course to keep their places until the playoffs.
Each side has lost just three of its last nine games, but to say such strong outfits will do well until the post-season isn't all that bold.
It's a bigger risk to say that the current New Zealand conference leaders, the Crusaders, will drop off the top of their standings before the normal campaign is through and will be replaced by a Highlanders line-up in desperate need of its All Blacks.
Both franchises have three games left on their slate, with the third-placed Crusaders taking on the Hurricanes and the Blues over the next fortnight, while Jamie Joseph's squad collide against the Chiefs and the Waratahs.
A journey to Sydney is daunting for any side right now, but the potentially devastating Highlanders will undoubtedly go into the onslaught with a nothing-to-lose attitude, and the stars of Aaron Smith, Malakai Fekitoa and Ben Smith should shine.
The real crunch clash comes in Christchurch, though, and the fates bring these two teams together for the final game of their campaigns, deciding whose season ends at the AMI Stadium and who gets to keep chugging on.
The Crusaders are renown for being particularly hard to budge at their Canterbury abode, especially when stakes are their highest.
But the Highlanders have performed admirably away to the Sharks, Chiefs and Hurricanes this season and hold the potential for one more display in their arsenal.
