I still don't understand what the difference would be though, so... swap em, and then? In the end what does it matter?
It would be just strange to change their genders now, it holds no purpose other than a few people who want to see it that way whatsoever.
I think that is why people don't like to see these things changed, it's such a triffling matter. That and we just have to believe Playtonic will do things their way as they are the developers in the end.
I couldn't care less about their gender, but we now have an image in our mind of the hero's. We get accustomed to this. It would be plain weird to swap their genders in the end.
Stop picking your nose
