Hmm, I guess my answer would be "not yet". There's barely enough room in a whole two movies for that ensemble cast to get much screentime, let alone a trailer. Heck, even the original novel doesn't do full justice to the entire dwarven company.
Judging from the trailer (which, admittedly, one should never do), it looks like this will be something of a three-handed tale between Bilbo, Thorin and Gandalf, with of course the most emphasis upon Bilbo. How far it goes in characterising the rest will remain to be seen.
