Snow elves are the best bet for a new playable race and even then I don't see it happening. More like wishful thinking.

I took it as maybe a Dwemer machination.
The Dwemer were very close in relation to the Chimer and they are by no means machine they are the current Dunmer.

All of a sudden, a new race comes out of no where! Woah! All of a sudden, the Dwemer have return from dark space and they're now a playable race! Woah! The Snow Elves have finally passed the SATs, they're now a playable race! Woah!

I meant what they are now, or were (the Numidium's got some issues involving time, currently being outside of it is one of the big ones), the metophorical 'skin' (though not literally the skin) of an attempt to achieve... reverse subgradience (hypergradience?).

PLEASE - No New Races!

There's already an excellent selection. I don't see new races adding anything to the game.

The only genuinely interesting race additions might stem from a new TES game that involves a portion of Tamriel and the entire realm/continent of Akavir.
