Don't quote me on this but I think I saw it quoted somewhere that they aren't a team yet. Also, in the page Team RWBY (just go search it in the search bar) it says that they haven't come together yet. So, short answer: not sure, but most likely, they'll form a team sometime in the future, most probably in the first few episodes (assuming they're going RvB format, there's no way they're going to pull all of it off in just one episode unless they do something very, very, very impressive).
