I'd probably state that maybe they are related, except they aren't sisters per say, but rather cousins (classic anime cliche), or maybe Yang's parents were friends of Ruby's parents (another classic anime cliche).

From the Red trailer I perceived Summer Rose as her grandmother (Little Red Riding Hood) who was probably Ruby's next of kin if her parents were considered deceased/missing. Since Summer Rose died, or had difficulties in caring for Ruby, perhaps Yang's parents pitied Ruby and took her in as their own, hence why Yang calls Ruby her "little sister." This goes along the fact if Yang's parents were friends of the family as well since that wouldn't be considered too farfetched.

I'm not saying that Crow is Yang's dad, but perhaps since Ruby called him "Uncle Crow" he has some sort of relation to Ruby's biological parents (or just another friend of the family), but for some reason or another couldn't participate in taking care of his "niece". I kind of have the feeling Ruby and Crow have this Harry Potter/Sirius Black relationship going on that we the viewers haven't seen how this will be developed.

It would be interesting to see if they ever decide to dive into that.
