Don't you think it's a
little too early to ask this? There's no information about DA3, no screenshots, no concept art, no nothing. It hasn't even been officially announced yet. Even if DA2 wasn't a complete disappointment, I wouldn't outright claim I would purchase it at this point.
Truth be told, at this point, I have zero interest in the Dragon Age franchise, outside of watching the train crash. The writers and developers have made it quite clear that despite all claims to the contrary, they really have no [censored] clue as to what they're doing. The series began and ended with Origins to me.
Though I guess as long as all of EA's products require Origin to run, I won't be buying any of their crap anytime soon.
The problem is, there was no cutscene. It was a fight like with any other enemy, and Gaider's explanation was that she wasn't really dead, merely unconscious - or something to that effect. Which is lame, because everything indicated that you actually killed her. It's acceptable that Anders faked his death because we only find a burned body, but when my character kills someone with her own hand I expect them to stay dead.
Eh, it's not really acceptable for Anders on any level either. Not only because there are several things that can result in his death in Awakening, but there are several things that can result in both he and Justice's death as well. It's also possible that the two never meet, it's possible to not recruit either of them, and it's possible for Anders to not even become a Grey Warden.
Truth be told there's a lot about DA2 Anders that's just plain sloppy. His presence in DA2 requires a specific set of circumstances for it to make sense. The timeline for his appearance in DA2 and Awakening doesn't make sense at
all. He has a completely different personality (handwaved by a bunch of crap that happens offscreen), and even has a different voice. They might as well have just replaced him with a new character and it wouldn't have changed anything.
