Vegas, SJS, ANA/Yotes/CAL would be my guess. Vancouver maybe, EDM lul
Anaheim isn't quite there, yet. They still have another year or so in their rebuild until they really threaten for a spot.
Vancouver and Edmonton are a crapshoot, but I don't really see anything with them that leads me to believe they are significantly better than they were last year.
Vegas has taken a step back, IMO. They lost Miller and Gusev (who didn't really play for them last year), and Fleury is another year older, and still has very little help in the form of a backup goalie to give him some rest. They finished with 93 points last season, and I expect about the same. I don't see them really being better than they were last year.
Calgary is still a top-3 team, but I don't see them replicating the 107 point season they had last year. Statistically speaking, it's far more likely that they regress back towards the mean.
San Jose takes a step back this season. They lost a big piece of their offense from last year (Pavelski), and Jones ended the year with a sub .900 SV%. If Jones has another year, like he did last season they could be fighting to get in as a wild card this season.
The Yotes added both Kessel and Soderberg to their offense, and are hopefully getting a full year from Chychrun and Raanta. If they stay healthy, it's feasible that they could be sitting anywhere from 90-95 points at the end of the season.
But again, this is just my opinion for how the Pacific will shake out.
