Why would Zinn want to join you, anyway?
The PC isn't going to get ancient artifacts any time soon. No discovering ancient lore or powerful magic scheduled.
The threat of Destroyers, who originally made Asura get out to the surface and teamed Vekk up with the PC, is long gone. There's no reason why any Asura would like to give up his laboratory, experiments and science just to accompany some bookah in his adventures around the whole world. Especially that Zinn has to plan his vengeance on the Council.
Maybe a new golem from Zinn and Blimm duet, but i doubt we'll get any real aid from the asura, party-wise speaking.
Sylvaris are also, obviously, excluded.
Charr? Apart of Pyre's warband, the only 'friendly' charr is Dune Teardrinker. I don't think he's going to give up his polymocking just to wander with some random meat and its mice.
A tyrian centaur? The only peaceful one i know is Ventari and he's obviously not going to travel the world with us, as his job in the world's lore is already known and, so to say, set in stone.
Maybe a changed dwarf then? One of those that survived the struggle with destroyers and came back to the surface to help the hero who once helped them. Yet even then, why? Is there any dwarf that might be alive by this time and would have any reason to join us?
I'd also rule out the usually-hostile creatures like demons (of all kind) and djinns. It would be just a bit weird to command a Margonite hero, even though it might be cool.
A tyrian tengu? I don't remind any tengu that might be even remotely interested in it...
A dredge from the retaken Sorrow's Furnace would be unexpected and, besides a dwarf, is the most probable out of the races mentioned so far. As a side note, i'd love to see - and take part in - retaking SF for the dredge during GW: B.
This leaves us either a norn or a human.
Out of non-human races, a norn is most likely to join us on dangerous adventures, to slay whatever comes at hand. Which norn NPCs know our PC and might be interested in travelling? Is there any norn, besides Jora, who owns us a favor?
The human population is big in GW1, so it would be useful to divide it into factions we know. Anyone of the Ebon Vanguard? Salma's allies - Bartholos? Dinas? A former White Mantle follower who'd like to repent for sins? Someone from Ascalon?
I'd rule out the whole Elona. Cantha is possible, but doubtful, as we'll get a hero at the end of HotN, and we know that HotN is not connected with the upcoming canthan content in any way - i doubt the new hero will be a bridge between HotN and WoC.
There are also non-ordinary possibilities - a spirit from the Mists, an undead XYZ, etc - but as Konig and Stumme hinted, the new hero is quite obvious, /facepalm-like obvious, so i wouldn't wander into those parts.
