Meh. It's basically what an unlicensed, slightly cheaper and worse clone would look like if NWN1 sold like hotcakes and people wanted to clone it. Everything it changes from D&D or from older D&D CRPGs, it makes worse. Shall I narrate the ways?
(1) Wizards don't have D&D magic. They don't have casting time, they don't have memorisation, they automatically cast lower level spells over and over again, spells 'level up' (Magic Missile II, III...). This has nothing to do with D&D magic except some spell names and damage specs are copied. What that means is your wizard isn't substantially different from your archer with special abilities in terms of how they play.
(2) As Darkpriest points out, there may not be any to-hit rolls. Combined with 1, this makes the game play like an MMO, and not like a D&D game. In a D&D game, you are constantly fighting AC / THACO / etc to make sure you can land a hit on your enemy and not get hit yourself; getting hit becomes a pretty big deal. Meanwhile your wizard becomes a glass cannon, meaning even if there was the problem that fighters are relatively boring, you, as a party controller, always had a decision to make every round. If everyone hits each other more consistently and wizards are the way they are, all those decisions go out the window; the very nature of the combat changes. It becomes DPS calculation and a matter of setting up an equilibrium where you do more damage than they do. The wizard can also be left on autopilot. The decisions about spells to use diminishes if some spells repeat and other spells are on a cooldown so they can also be used again.
This results in situations like that boss fight, which is very similar to how boss fights in DA:O work - you find a combination where your DPS is higher than their regen/heal and their DPS is lower than your regen/heal, then you just sit there and rinse/repeat ad nauseum until you inevitably win.
(3) Given the way people ice-skate all over the place all over the video, there won't be much in the way of tactical positioning going on, except at the beginning of the battle. This is of course endemic to the 3D era, but Pillars attempts to address it with engagement, and in any case, other games like NWN2 and DAO weren't this bad with the skating. This reduces the importance of space, and once again, makes combat fairly same-same and repetitive.
(4) The town looks nice enough but generally low textures abound, artistic style is super-generic (check the item icons or the models in the inventory window, as opposed to the beautiful paper dolls and item graphics in BG2 or even the ones in Pillars). It looks like dialogue will be kept to the very basics with the Biowarian Three Choices, but the dialogue probably lower quality than Bioware.
It can still turn out to be a decently fun game, especially if you liked DA:O, especially if you like MMOs. A D&D game it is not. Is it worth buying? Well, I liked DA:O, but this probably will be a lesser clone, and not as good as DA:O. I also don't like the dishonest and frankly stupid way they came into the room shouting OMG D&D IS BACK GUYS when it is hardly the case. I doubt this is worth more than $10.
