One (of the many) thing(s) I hated about Mass Effect 2 was that your companions were now limited to their default outfits, some of which were extremely cheesy or campy, or just unpractical in the extreme (Miranda and Jack come to mind).
Hopefully we can:
a) still customize the armor and other gear of our companions (that also changes how they look in the game)

still customize how Hawke looks (facial features etc)
I admit,

seems to be an obvious "yes", but I haven't seen it mentioned yet. Perhaps I just haven't read enough of these preview articles?
