Today on Twitter, David Silverman (marketing director at BioWare) said these things:
"@SilentKittyK the CE of #ME3 has both #FemShep and male Shepard on the box."
"@ChrisCrowdly there will be a #FemShep trailer. We actually had a meeting on her yesterday. We are working on the look now."
He'll have to do better to redeem himself for the whole "awesome button" thing, though.
