It's a bit worrying that in the provided video, the warriors, previously stated to be river (spring) spirits, are called water elementals. No, of course, for the sake of a demonstration video, you could simply rename the unit for one time to continue building intrigue, because it's not that difficult.
But the question arises: what does the information leaked in January actually represent? Personally, I have three possible answers.***
1. There was no race initially. What was shown to players a month and a half ago is just a combination of approved artwork with unapproved (or fan-made) artwork, and people took what they saw as the fifth Faction.
2. Sanctuary was split into neutral units due to the data leak. But this is highly unlikely, because the leak of the artwork occurred in January, that is, three months before the official release of the sixth installment. I don't think the developers would take such a step just because of the leak, because then they would have to abandon the already prepared material (and in January it was definitely ready, because by this time, as a rule, all the key elements of any game being created have already been developed). There simply wouldn't be enough time to form and, accordingly, implement a new race. And if there was, the Faction would be noticeably underdeveloped. This leads to either the first or the third version.
3. The water race is still waiting for its official release, but the clever developers continue to carefully hide (mask) any data about the authenticity of the fifth Faction in order to generate interest in the game being developed. If Sanctuary is really included in the list of Factions in the sixth installment, then, perhaps, the race could have been calmly presented in February if it hadn't been for the art leak. Now we are being punished for someone's indiscretion.***
Of course, it is quite possible that the Faction exists. Perhaps, due to the leak, it was moved from the main version of the game to an expansion. Or the water elements simply look very much like river and spring spirits (because the color of the "headgear" has been changed)...
In general, there's no point in guessing, it's already impossible to change anything. We will get what we get this coming spring. But let's hope for the best. :)
