Chiefs & Crusaders now eight points clear of third-placed Brumbies, I doubt they can be caught regardless of what happens when thry meet in Week 13.
Likewise Brumbies & Reds look to have third & fourth pretty much locked in with their Week 14 match likely deciding the order.
Hurricanes, Force, Waratahs & Moana can still make the QF but barring a miracle Blues & Highlanders are surely gone. Drua have three home games coming up but even if they win all of them I think ninth or tenth is the best they can hope for.
2nd is probably still open given the Crusaders play the Brumbies as well as the Chiefs - if they loose both of those their lead over 3rd/4th evaporates (depending a bit on BPs), particularly given the Brumbies game is effectively double points in that calculation. That said, I do think them and the Chiefs finishing 1 and 2 is the most likely outcome from here. Reds and Brumbies finishing order will probably be decided by their head to head match up, though both have some other tricky games coming up.
Hurricanes are firming for the 6 - even if they lose to the Chiefs and Reds, wins against the Higlanders and Moana will probably be enough given their positive points difference has them 48 points ahead of the nearest competitor (Moana). A few BPs wouldn't go astray though, pick up enough and they may even squeek in with just one more win.
Blues having match ups against the Force, tahs and Moana does keep them in touch for mine - even if the Hurricanes lock down a space that still leaves one space open and the Blues are within a win of all those teams they play (BP win in the case of the Force), so they can absolutely make up the ground. Lose any of those games and they're done though. Blues v Force this weekend will be huge, Force win and they're in the box seat with the Blues gone, if they lose than they'll likely need to win their remaining home games (Brumbies, tahs) with at least a couple of BPs along the way.
Moana and the tahs are dropping back for mine, though both still have a solid say in their future given they play some of the sides they're competing with. Tahs points difference and inability to pick up bps may sink them though, they'll likely have to get their on wins alone the way they're going.
