Actually there's been a good deal of PR in these weeks, character vignettes, lots of previews, even a spot aired during 24 IIRC.
As for the reception, the pre-order charts last time I looked were moderately positive, the comments on the gaming sites were basically concerned about graphics and AI, not to mention the usual 'it looks too much like Mass Effect', but it's not the first time I see stupid comment like that, they were always there even for Dragon Age and it turned out a success. Mind you, it was backed up by EA and I doubt AP will have the same success, but I also doubt it will fail.
