Indeed. Besides, we have an "almost confirmation" of Tali returning, as she was romanceable. I think that any romanceable characters will probably be coming back, as they are (or rather, can be) a big part of Shepard's life. The big question, in my opinion, is whether or not the non-romanceable squadies, like Zaeed or Grunt, will be coming back.
