Yeah, I'm taking this save game transfer details with a pinch of salt. No expectations. In Dragon Age 2, the effects was laughable and from experience with ME, we know that most choices made in previous games doesn't carry much weight. They simply replace the character in a story segment with some unknown, modify the dialogue a bit and everything else stays the same.
I'll still get Dragon Age because I enjoy the games but I have no confidence in any promises Bioware makes. With Dragon Age however, the story isn't as deep as with Mass Effect so I'm not much bothered with the save game transfer to begin with.
