That is, assuming Yang and Neptune were after a giant mech in the trailer clip where they're riding Bumblebee.

A few days ago, I noticed in the clip where Yang and Neptune are riding Bumblebee, Yang is wearing that white outfit from the clip where she walks into Junior's club. (Refer to gallery below) Look very closely at her sleeves and leggings. Black sleeves with yellow cuffs that end at her elbows. Black leggings, though in the motorcycle clip, we can more clearly see Yang's burning heart symbol on the side. And she has the purple scarf. At first, I thought she just kept the purple scarf, like it meant something to her. Now I'm kinda sad to find out she's just still wearing the outfit it goes with.

Meanwhile, in the clip where she and Weiss are on that highway, where Weiss makes the cicle of ice, and the clip where all of Team RWBY are facing the giant mech, she's wearing her usual combat gear.

It all looks like the same highway they were on at the very end of the trailer after the title card, considering it has the same bridges in the background. So, the scene where Yang and Neptune are on Bumblebee is in the same place, but at a different time than the scene where all of Team RWBY faces off against the giant mech, possibly on the same day that Yang revistis Junior. This means they may face off against a giant mech more than once.
