Show me the male zombies in speedos and I'll excuse the female zombies in bikinis.
Don't get me wrong, I love the game. It's on my GOTY list, I just won't support a rerelease with new graphics that doesn't fix a problem I had with the game. If the protagonist was player choice on male or female then I could excuse stuff like that outright. But I'm no longer buying new IPs or series with new protagonists every iteration that don't let you choose your gender and I will not support games that don't respect women either.
You're gona get shitstormed...
But regardless, I'm all in for sexual equality in games.
The problem is a similar one with the depiction of black protagonists in American movies (or lack there off). They are trying to appeal to the broadest demographic which in the majority of sivilized world (or at least where they can affort to see movies legally) are whites, thus most action flicks have white protagonists.
A similar problem exist with Female characters in videogames. The average gamer is considered male, and the female gamers don't always openly admit it or just play casual crap, so when a designer (who's also likelly male) is building the game, he has that audience in mind, so it makes sence to build the game from a male's point of view, and have female characters be little more than eye-candy. Also complaining about female videogame characters for being skimpy and oversexualised, is like complaining about the human rights of Oliver Twist.
All is not all bad though. In recent years, female gamers have become much more relevant, and a change is already visible. Most western RPGs give an option for an equally strong-looking female protagonist, and some developers like Dontnod Entertainment are taking chances on that. Afterall, bald muscular space marines have practically become a game joke by now.
The change is happening, but don't expect it to be instant. Developers are still in majority male, and when they attempy a female friendly game, it's usually their definition of what women want, while at the same time trying not to alienate their male audience.
Just enjoy the game and support the industry.
