I do support House's request to have a trailer including both the male and the female PCs. I participated in a thread for about 6 months requesting a trailer for the female IQ. Some of the folks here I debated with, and they all gave me food for thought. I may not have always agreed, but the folks I debated with really made me think about why I felt the way I did. Good debates all around.

While this is important to me, at this point I'd rather they keep the new ME:A PC gender neutral. My main thing these days is that I'd like to see someone that isn't white. It can be done by using something as simple as lingering shot of a hand. Men can have delicate hands and women can have large ones, so that would work for me.
I do think there needs to be some more representation of a female PC in RPGs that allow for customized characters. We're getting there though. However, a quick google search told me that
54% of Latino gamers are more willing to buy a game on the first day. Enough with the "white as default" on PCs in games that have a diverse mix of ethnicities (like the ME series. Not talking about TW3.) FB is a beautiful engine, so I think BioWare should show it off.
Honestly, at this point, I'd rather see a PC that wasn't a white guy. Male or female; it doesn't make a ton of difference to me. I would prefer a lady, but in a setting where there is such a mix of backgrounds, I would actually be happier if they showed someone that wasn't white for once.
In the end though, I'd rather see the more ionic N7 armor or the ARK armor than any sort of gender or skin coloring. I'm way more curious about what the new armor is going to look like when it's finalized than I am seeing a male
or female PC. Having a female and male PC trailer that weren't white would be nice, but a gender neutral trailer showing off the new armor would be my absolute preference.
Just my two creds.
