The Elder Scrolls 6?

not Dwemer, but Dwarves. Maybe in Bethesda, Dwarves = Hobbits.

In TES, there are many other races that seem to exist but rarely appear (except for some of them as NPCs): Ayleids, Maormer, Skaal, Reachmen, Imga, Kamal, Sload, Tang Mo, Tsaesci, Rieklings, Ice Giants, Centaurs, Dreugh.

There are mentions of them in books, dialogues, and so on.

And here, suddenly, there are halflings, about whom no one has heard or seen. And nothing is written about them in any book. And they decided to add them as a full-fledged playable race. That just can't be.

the first drafts, like sketches and simple "bare" models (without animations), are quite likely.

Even the simplest things for a new game are foolish to start doing six months before the release of a buggy and unfinished project. And even immediately after the release of TES 5, it is foolish to immediately start TES 6, because the team should patch the project and develop add-ons and DLC.

taking into account the 1.5 years from the development of Skyrim (they said that they were working on it in parallel), it will be 5 years.

I took these years into account in the calculations. This "news" claims that the game has supposedly been in development for 1.5 years, and in 2 years it will be released.

It's clearly fake news. Can't you see it?
