while I Dak isn't at the top of my list - I do find it very good news to hear he is coming, along with the CC pilot - I will nab them both (and an extra of the CC pilot of course).
But with all of these products coming out now focused on the release of this AT-AT (Snowspeeder Luke, AT-AT driver, AT-AT commander, Dak, Snowspeeder, etc?), I am kinda hoping we see the Snowtrooper Officer guy to go with it all. While he is not high on my want list, like Dak, all the justifications and them some are out there to put this guy on the shelves right now imo.
I would think that since there are so few differences between him and regular trooper (new headsculpt. rank badge, and I think he is all white), this would be easy/cheap for Hasbro to do.
