I think there's still plenty of room left for more female voice actors and better roles for women all round in games.
There does seem to have been a trend in RPGs to cast women as either housewives, helpless, witches or whores, which does get a bit monotonous. I've lost count of the number of games that insist on including a brothel. Even the great Planescape Torment which had some good gutsy female characters insisted on having the street scenes crowded with an extraordinary number of 'harlots'.
It seems as if game makers assume that their target audience is all spotty sex-crazed adolescent boys. Yet polls on forums always seem to show a strong older demographic with the average age being something in the high twenties.
(Apologies to any resident spotty, sex-crazed adolescent boys on the forum - I do understand that your cravings are real and not to be made fun of. However, the satisfaction level afforded by tiny pixellated boobs is exceptionally low..... <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> )
It's coming, just more slowly than some would like (better roles for women in games, I mean... )
