Just something to add. I doubt Monty has finished animating the latter half of the volume yet. So, the fight with the Mech is almost certainly the mid-season battle (the equivalent to the fight with the two giant Grimm in volume 1). I strongly suspect that there will be an even more kick-ass fight in the last episode, possibly includng the long-awaited four-on-four between RWBY and EVIL.

I also suspect it will include a cliff-hanger to keep us panting for volume 3.
