The new Liara, with the smaller boobs, is more "realistic".. as realistic as a blue alien hermaphrodite can be, anyways.
I love it.. now give us a Garrus, Grunt or Mordin
, or if you're only doin' the ladies... a Tali or Kasumi (chances are we'll see Ashley or Miranda first, I'd wager).
If we even see any more of these.. let's hope so.
