Well, I've finally managed to play through the DA2 demo, so here's my thoughts on it:
Graphics: Not something I consider all that important, but will start with it since it's the appearance of the game that you first see. Having seen screenshots of it before I went in with the belief that I was going to hate it, that it was going to ruin it, and even had how I was going to describe it planned out, involving such comparisons like 'It's as if Bioware skullfucked me in the eyesocket with their dick' and other such colourful adjectives. It's not that bad. It's not that good either. It's just meh. I'll leave you all to decide whether that's better or worse. No, I won't actually, it is better, just not as good as DAO (which I considered bland as it was). It's not like it couldn't have looked good with the art style they went with either, but the settings themselves just looked bland. Considering there isn't any day/night schedule I'm really surprised they didn't start the game at sunset so that you could have a blood-red sky and scenic battles with the sun at your back... Oh, and Isabella looks like a transexual suffering from some skin condition, had to be said.
Characters: I don't know if it's because they are trying to be dark and edgy or because they personally hate me but Bioware seem intent on making me dislike the characters in this game. Coming away from it I don't think there was one character that I felt like I would want in my party based on their personality, they were just so unlikeable. They all seemed to just have a cock waving competition throughout the game, trying to out-sark, out-bitch or out-shout each other at every available opportunity. They were a bunch of pricks to be honest.
Hawke: Played female warrior, will try male mage in a mo, but no I don't like the PC VO for DA2. It doesn't feel like my character, and it doesn't feel like a character in it's own right, feels like a mannequin that's doing it's own thing. I don't know if it was because Shepard clearly had a role predefined for you (he's a soldier in the navy for whom you choose one of three backgrounds, and has the personality 'soldier') or if it's the VO work (probably both actually) but it works in Mass Effect but it doesn't work here. Just my opinion no need to go spreading it around as Joker would say.
Flemeth: I liked Flemeth in DAO, I liked her alot in fact, more than Morrigan (but then I despised Morrigan) and I liked how she was essentially an all powerful dragon in what looked like a crazy cat woman's body. It gave her a mystique. I'm not sure what I'm meant to make of MILF-dragon, except that it's further evidence that gamers don't seem to like authentic ugly old women in their games but instead everything has to look like it would be bangable.
Setting: Oh look, they're going for the 'underdog' approach again. Oh look, Chantry bad and picking on poor apostrates again. Not much more to say here really.
Gameplay: It's not bad. It's not good either. It's also not the same as it was for DAO on PC. The lack of the isometric view kills any attempt at using tactics for me. I'm sure I'm just supposed to get used to or something, but it's not as good. I want to look down on the field of battle, and I don't want to be tied to a character while I do it. I also just hacked and slashed my way through it, and didn't even bother switching characters. I liked controlling the characters in my group, but this doesn't encourage tactical playing with the whole party, which wouldn't be too bad if there was a lot to do with your character, but I found myself waiting around a lot of the time. I think I have worked out why they added the manual attack button: to give you something to do.
It must sound like I hated it, and considering that I had expressed concerns before going in I'm sure many people may think that I had already made up my mind beforehand and am just nitpicking and what not, but I did try to approach it with an open mind, and I have gone into a game before expecting to hate everything about it and come out pleasantly surprised and thirsting for more. I don't hate DA2, I can see why others may like it, hell I may even recommend it to people I think will like it, and I can see the potential in it, but for me? I'm not getting it on release, and unless I see something after release that changes my mind I may not even get it when the GOTY edition comes out like I originally planned.
Again, this is just how I currently feel, and while I don't expect to get the full experience from a demo it hasn't piqued my interest any, so well there.
