The entire World Cup squad will meet in Brisbane - the unlucky ones headed home - and Jane tweeted on Monday that he was on his way to Brisbane. But the Wellington wing is a self-confessed joker (he says on his Twitter page "I like to joke around and have fun") so while it's dangerous to assume anything with Jane, the smart money is on him making the World Cup squad.
Messam has always struggled to establish himself in the All Blacks and, while he did nothing wrong against South Africa in Port Elizabeth, is more of a luxury than a genuine weapon. He lacks the size of other No 8s and it's hard to see where he fits in the All Blacks mix.
Vito was thought to be out of consideration as little as 10 days ago but his callup to travel to South Africa, as well as his bigger bulk, appear to have tipped things his way. His likely selection could be viewed as the most unexpected.
A bolter like Matt Todd or Luke Braid was a long-shot and Adam Thomson will retain the back-up No 7 duties. He was unconvincing in the role against the Springboks on Sunday morning, but Henry and Co weren't likely to include a newcomer at this late stage, which meant it was a straight choice between Messam and Vito for the fifth loose forward spot.
There was plenty of teeth gnashing from jittery fans around Colin Slade's nervy performance in Port Elizabeth, which prompted suggestions Aaron Cruden should be brought back into the fold, but the selectors aren't prone to panicking. They seemed to make their decision on Dan Carter's backup when they picked Slade for the Tri Nations despite his paucity of rugby this year and they will be mindful of the fact Cruden has also had his struggles when in a black jersey.
A decision will need to be made around Anthony Boric's fitness. The North Harbour lock hasn't been sighted since injuring his foot in June but is close to full fitness and will turn out for North Harbour on Friday. His form for the Blues and more particularly on last year's end-of-year tour should be enough to see him get the nod ahead of the abrasive Jarred Hoeata as one of the four locks.
The last area of debate was around the front row, especially after the All Blacks buckled in the scrums against the Springboks in the weekend, but Afoa and the fit-again Tony Woodcock are believed to have got the golden ticket ahead of Crockett.
Crockett is unlucky to miss out after an excellent season but Woodcock's experience is hard to ignore and Afoa's greater versatility - he can play both sides of the scrum - appears to have been the clincher.
It is a measure of New Zealand's place in world rugby that quality players will be left out and it should give fans confidence the All Blacks will, finally, win another World Cup. The defeat to the Springboks shouldn't cause too much alarm. It's hard to see the All Blacks play that poorly again, especially with some major firepower to come back in, and defeat will only sharpen the minds.
Not that they really need to after 24 years of pain.
