Some facts from the Russian-language developer stream:
1) The skill system is from Heroes 5, but simplified. There are no situations where a secondary perk requires three perks from other skills. Reason: they don't want players to spend too much time optimizing their skill builds.
2) There are templates, including ones in the style of Heroes 5. Like the Universe faction.
3) There will be no water tiles at the start. Which is not surprising: they are rare in PvP.
4) There are unique faction skills, like Necromancy.
5) There are neutral spells and spells from four schools. And these are not elements.
6) The AI will be divided into a PvP-focused combat AI (which is a bit simpler) and a PvE AI, which won't fall for cheap tricks and will act like a player with a normal skill level on the map. That is, it will have a main strategy, chains of actions, and will focus on controlling the center of the map, etc. All of this is relatively modern compared to the game's 20-year history.
7) They explained the visual style: everything is for the sake of performance. They could have made a cooler and even fully 3D game, but they chose a more durable and less demanding option.
8) The game will have a reasonable price at launch, in the "buy once" category. However, this question still depends on Ubisoft.
9) They put a lot of effort into the random map generator.
10) They thought a lot about how to combat cheaters.
11) As a bonus, they showed the camera zoom levels (they are quite extensive) and the interface (it's in the style of Civilization, but a rather early version, so it might be changed).
12) Timers, replays, and other features are also available.
13) There will be no Capital.
14) There will be a rating system from the start for each game mode.
15) There are hero specializations.
16) Sulfur has been replaced with another resource.
There will be the ability to zoom in and out on the map:
