DAO, DA2, DAI are somewhat CRPG with action, and your choices carry over(mostly, they cheat quite a bit actually) to the next game.

DAV will be an Action-RPG with a gameplay similar to the Guardian of the Galaxy game with companion doing shit and they will not carry over any choices, actually they will let you create the protagonist of DAI and let you choose 2 things that affect the antagonist of DAV. They will bring old characters like Morrigan and Varric but whatever happens with their questline in the previous game will be ignored OR they will make a headcanon, is not clear yet. For example, Morrigan has 2 personalities depending on whether she had a son or not, but the game will ignore that choice.

What is most infuriating is that in DAI you have a lot of choices that they seem really important and groundbreaking but don't directly affect DAI so almost everyone was expecting that these will have a purpose in DAV, but oh well too costly to do that, let's just do the bare minimum.
