I've avoided posting in these sexism topics before, because they're always so far off the deep end that finding any common ground is clearly impossible. But seriously, people are pointing to WoW character models as pandering to male sexual fantasies?
These models aren't pandering to males; they're simply designed to appeal to people. Not just men, women too. When my guild moved from EverQuest to WoW, I wanted to play on the Horde side. Several others in my guild agreed, but in the end we were overruled; the women in the guild refused to play Horde because the female character options weren't attractive (ie, sexy) enough relative to the Alliance options. This wasn't an isolated phenomenon; many other guilds ended up on Alliance for the same reason. I ended up with characters in both factions, and Horde had far, far fewer women playing than Alliance did. PvE servers were dominated by Alliance, often outnumbering Horde by 3-to-1 or worse. One of the primary reasons for the creation of Blood Elves was to address this imbalance. (Female Blood Elves became extremely popular among the few women who did play on Horde.)
This idea that female character models designed to look attractive are alienating women from gaming is pure fantasy. "Hyper sexualized" designs maybe, but that's not what WoW is doing. And even then, take a look at Dead or Alive. Now there's a game that sexualizes its female designs, and you know what? It's a fighting game with one of the largest female fanbases out there. When I've played DOA with female friends or with my sister, they don't take issue with the female character designs; in fact, they like those designs. My male friends mainly played the male characters in DOA; it was my female friends who liked the female characters.
Another example: Fable II. When you add points to strength in that game, it alters the character model to make your character look stronger and more powerful. Both my girlfriend and a female friend of mine hated that. They wanted their character to look feminine, not powerful. My girlfriend ended up using potions to remove the points she had put in strength so she could look feminine again. Even though it took her ten times as long to kill anything, she wasn't interested in playing an overmuscled female character.
Finally, this isn't some phenomenon that's unique to gaming, and it isn't unique to male artists. Female fantasy artists have been painting sexualized women for decades. For that matter, female artists in other genres have been doing it too. Many of the biggest offenders are female when it comes to the sexualization of women by artists. Such art is often popular among female fans, as well. If you want to wage a crusade against the whole thing fine, but you're fighting a lost cause.
