Yeah, this is what I thought the first time I heard she was being turned into a woman for the Ultimate Universe, that basically it was about making it all just sexier for the fanboys. Not only is Scarlet Witch a bit kinky and suspiciously close with his brother, she's also gay for fembots! Ugh.
It is - or could be - interesting that they wanted to make Vision female. But so far I don't seem them actually doing anything good with that, other than fan service. Why give the character any assigned gender at all? It would have made Wilson's feelings for Vision much more interesting. Now it seems he's falling for the robotic thigh-high boots and metal boobs.
