Does anyone think that there will be a cambian race option maybe under the tiefling page possibly? Or maybe a U.A. Race. What are yourbthoyour  about this fellow DMs and players.

What is a cambian?

i think he means cambion.  the offspring of a planetouched woman (almost always a tiefling) and a tanar'ri.  after the spellplague it was used more generally to describe the offspring of a humanoid female and a devil.  also sometimes used to describe a half-fiend in general

So basically a Tiefling? Or would it be closer to devil than a playable race?

Or to bring it down to 1 question: what would it be able to do that the 12 or so versions of Tiefling can't?

 There is a version of it in the MM Cambion - don't know all the Tiefling variants to know how this is different.

Cambio, cambias, cambia, cambiamos, cambiais, cambian.

It just means people who are changing :)

It used to be in 1st/2nd that a cambion was the offspring of a demon and a human. There was a significant demon/devil distinction back then, so a devil/human offspring would be very different. I don't think there's much care given to that distinction anymore, is there? Isn't it all just 'Fiend', pretty much? (I mean, the MM has different kinds, but it seems like 'Tiefling' captures offspring from them all.)

 Okay, so strip it down from a CR5 monster into a playable race, and you have a winged feral Tiefling.

Cambion are more Fiend then Mortals, a bit like a First generation offsprings and they fully take on their Fiend parents.

WHile Tieflings are mortals that has a Fiendish Legacy somewhere in their lineage, often Tieflings are the 154862th generation of someone who did Kinky things with a Fiend.
