Not to rain on anyone's parade, but we shouldn't take what we see here as being indicative of what will happen in the series... or at least this volume, at any rate.

I mean, look at vol.1's opening compared to what actually happened in that volume: did team RWBY fight that "Black Sphere"? or did we see Jaune gaze at the statue in front of Beacon? Heck, we haven't even seen Yang's motorcycle in-show!

My point is, RWBY's openings are very much anime-style openings that act more like pseudo-introductions for the characters and teasers for the awesome-ness that the show promises. Unlike most western CG openings, which tend to use footage form the show itself for the opening. (RWBY's use of recycled animations for the first op did nothing to reduce that)

Of course, that's not to say the things we see here won't happen in-series; just that, if they happen at all, they probably won't happen like how we see them here. (take Pyrrha's fight with team CRDL: I would imagine it's supposed to be a team-on-team fight from the tournament, but Cardin instructed his team to gang up on Pyrrha while she's alone. Maybe.  Just a guess.)
