Yeah, that surprised me too. I thought I'd try to get some info of my own on that subject, so I asked my friends at school if they had played ME2 only. Of the 5 that have, only 2 ever got around to finishing it, and the others lost interest, whereas everyone I know at school who has ME1 and 2 has finished both, so I'd say that there's a relation between imports and completion rate.
