I personally am not worried for one reason and one reason only.
It got delayed.
I think a major consensus from people on DA2 was that it was a rushed cash-in, and it might also be BioWare's worst RPG, which says a lot because DA2 was still pretty good. But now that it's been delayed, we know BioWare has learned a lesson and is taking it's time on ME3, hopefully meaning we won't see cookie cutter locations, like the ones of or DA2 or ME1 (Which had it, mostly in the side quests). It's still BioWare too, so we'll undoubtedly see wonderfully written dialogue, greatly sculpted characters, and so on.
Also Garrus is back and in your party, so no one should be worried.
