I think people confuse "race" and "species". Unless all of them can interbreed they are different species.

Joerg Bergmeister vs Jan Magnussen--oh you meant peoples!?! Right. My bad. I'll go with the normal ten, though I think it would be cool to at least meet a snow elf in there somewhere.

Personally, I am perfectly fine with the current 10 races we have, but I think it would be cool to implement a sort of origin choice, where you choose what variation of your race you are, in a way sort of similar to Dragon Age. Say you want to be a Khajiit... you pick what kind, out of the ones stated earlier.

wont work

Riekling race, haha, hate thoose little!!! ......

Has it been officially announced that it's the same ten? I know it probably will be, but without proof then I think all your points are invalid.

This is not WoW.

The thing is there are only a certain set of races. They don't just make up races off the top of their head and slap them into the game. Many of the other races of Tamriel went extinct or disappeared. Ayleids went into seclusion and only a small group of pure-blood Ayleids exist anymore and they hide in the heartland woods of Cyrodiil. The Falmer went extinct. The Dwemer disappeared. It's just that there isn't much else in Tamriel that would be counted as a humanoid that a player could play that would fit into the story. I mean, no one is going to ask quests of a Ogre or Tsaesci. (Even though the Tsaesci is are from Akavir.)

Read the game informer article, Page 51. I quote "Players will still be able to craft their Hero from 10 unique races, but facial and body features will be entirely customizable."

Same 10. Sorry pal, all of his points are Valid. Only thing that may possibley happen is them removing Imperials and replacing them with Falmer.

As long as the lore is good and they can make a new big island for it or some other origin and it works thats fine. But it can not be rediculess we can not be a dragon race.

The games take place on Tamriel, which means the player should play a Tamrielic Race. The Tamrielic races are

Human (And the various subsets)
High Elf (Including Heartland High Elves, the Ayleids)
Dark Elf
Wood Elf
Khajiit (And the many types of Khajiit)
Argonian
Orc
Chimer
Falmer
Dwemer
Hist

The Ayleids are nearly extict, and on principle do not interact with the rest of the world
The Chimer were all turned into Dunmer (with the exception of the Tribunal, who are now gone)
The Falmer did go extinct, though for reasons unknown
The Dwemer vaporized into nothing
The Hist are trees.

Outside of Tamriel, there are other races.

In Pyandonea, there are the Maormer, aquatic elves. They live in nice tropical islands. They are also hostile to Tamrielic races.
There are the Sload, of course. They are very hostile.
There were humans in Akavir, but they were allegedly eaten or enslaved by...
... The Tsaesci of Akavir, snake people. They have interacted with Tamriel before, and two even ruled the empire as potentate before being assassinated. But they are very much hostile.
The Kamal, snow giants of Akavir. I imagine they'd sooner crush your puny villages than to try and interact with them
Ka Po' Tun, a race similar to the Khajiit, except exclusively tigers, who live in Akavir. They are also attempting to become dragons. Their leader, Tosh Raka, succeeded. Their allegiance is less certain, but it was mentioned that they have ambitions of conquering Tamriel.
Tang Mo, a benevolent race of monkey people in Akavir. They are described as being kind. They are also allies of the Ka Po' Tun.

For any possible races, it would have to mean inclusion of another race outside of Tamriel, where the people manage to integrate with Tamrielic society. Or another variant of human races, all of which are pretty established. Or perhaps splitting the Imperial race into further subsets (Colovian, Nibenese, etc) but they are only different in terms of culture, not racial features. Or one of the humanoid subsets of the Khajiit. Some Khajiit are more human than others. Or perhaps half elves, a role that the Bretons already fulfill to an extent. That leaves little room for possibility, and creating a new race would just be more trouble than it's worth.
