Head coach: Vern Cotter
Assistants: Scott Robertson/Jamie Joseph
The All Blacks have pretty much been untouchable since their 2015 World Cup win. So after they take out the three-peat in 2019, Vern Cotter will come in from France as a chance to freshen things up at the helm of the All Blacks juggernaut.
Despite mixed results with Scotland, the side largely improved under his watch and he brings a new approach with knowledge of the gradual improvement of Northern Hemisphere rugby.
Scott Robertson will have also tasted success with the Crusaders by that point, he will come in as an assistant to eventually move up the pecking order when Cotter decides his time is up.
Jamie Joseph makes sense as a second assistant after success with the Japanese side and a Super Rugby title to his name.
With a taste of how things work at international level, Joseph and Robertson would suit the style of Head coach Vern Cotter.

Head coach: Joe Schmidt
Assistants: Chris Boyd/Tana Umaga.
Two Six Nations titles, a historic win over the All Blacks and a 65 percent win record with Ireland is a fantastic record for Schmidt, and he'll likely take them deep at Rugby World Cup 2019. After which, he'll be the perfect All Blacks head coach.
Newsflash: The Hurricanes won't be bad anytime soon so Boyd will quite possibly have another title under his belt and be ready for the next challenge when his contract expires at the end of next season.
Umaga is clearly a coach on the rise, although his appointment would hinge on his ability to get the Blues back to the playoffs in the next few years.

Head coach: Ian Foster
Assistants: Jamie Joseph/Chris Boyd
If you read between the lines in comments out of New Zealand rugby, then I think it will be Ian Foster.
Steve Tew has said they'd like to have the next head coach involved in the 2019 campaign. Well, that might rule out Joe Schmidt, Dave Rennie, Warren Gatland and Vern Cotter. They're all under foreign contracts during that time.
The succession from Sir Graham Henry to Steve Hansen worked, so they might want to do it again, especially with all the success Hansen and Foster have had together.
On the other hand, if they don't win the 2019 World Cup then all of that could go out the window.

Head coach: Ian Foster
Assistants: Todd Blackadder/Chris Boyd
Warren Gatland will likely return to New Zealand after the 2019 Rugby World Cup but due to his time spent in the All Blacks coaching team, Ian Foster will get the head coaching gig ahead of Gatland.
Meanwhile, after Todd Blackadder's successful stint in Europe, he'll come home and get the assistant coaching role.
Chris Boyd will get the nod in the other assistant role after a very good tenure at the Hurricanes.

Head coach: Dave Rennie
Assistants: Leon MacDonald/John Plumtree
2019 will see Steve Hansen depart as arguably the greatest ever All Blacks coach with back-to-back World Cups under his belt. It'll be a hard act to follow, but I think Dave Rennie's the man for the job.
He has a great relationship with several of the leading All Blacks including future captain Sam Cane, Brodie Retallick, and Aaron Smith and he would work well with Leon MacDonald, who is rising through the ranks as an innovative backs coach.
John Plumtree has whipped the much-maligned Hurricanes forward pack into one of the best in Super Rugby so he gets the nod in my book.
