Well Bioware needs to shape up, just because EA is treating them like kings doesn't mean they should be lazy. Mass Effect 3 is gonna be the last game of the trilogy, and the least thing Bioware should do is not leave the female versions aside. To me, it's kinda ironic how they can have enough resources for alternate relationships but not girl turians, salarians, drell, etc.
They definitely do. I really hate that they haven't put in any effort to make female turians or batarians, because there's really NO reason they shouldn't have shown up in ME2. (ME1 I'll let slide since it was the first one and probably lacked the larger budget of the second one) Since we're visiting the Salarian homeworld in ME3, I expect female salarians, turians, etc.
Adding female versions for the aliens would defiantly add variety and diversity. I mean that's what made the first Mass Effect so awesome because of it's universe. If they add them, then Mass Effect 3 would have an automatic win.... and a batarian sqaudmate.
