Technically it is not fully confirmed, but Tully Ackland released an image on his twitter page which was part of a male quarian image, he noted "coming soon to a multiplayer near you". This image bears perfect resemblance to a Male Quarian in that the half-hood and helmet wiring is visible, as well as part of the visor. Note that the image was taken down and Ackland had his account suspended after, take that how you please. If you want to see this image, you'll have to scour in the BSN to find it.

Side note: Some chaps are claiming to have found game files which, IIRC, were named "MPDLC01Jungle" and "MPDLC01Goddess". Also somewhere on BSN.
