With the conclusion of V5, We can only assume that well be seeing what was mentioned. We dont really know how far things could go with the series, however, I do feel like we're in for a much longer ride than expected. Now that Team RWBY has been reunited, team JNR is down a member but with Oscpin in the picture Im sure Team JNR will adopt him as Oscar continues to develop as a warrior, and Oz continues to manifest his Reincarnation.
We will probably be seeing the group cover ground to Atlas to loop Ironwood into whats happened. There's also a possibility we could see them all travel to Vacuo to protect the other relic, seeing as how Atlas is pretty we defended. Vacuo seems like the more appeasing choice seeing how the group could repel an attack in Vacuo in V6, and then move to Atlas to mobilize against Salem in a potential V7.
Now, as far as character development goes(tangent warning), I can almost assure we will be seeing more of Jaune as his semblance comes to light and plays out in the groups battles. Ruby will most likely learn-or be taught-to harness her true warrior potential in the very first Awakening of the series. Oscar will most likely continue to train in combat and harness his Aura. There's really no way of saying if well be seeing a Semblance due to the fact that he is the host for OZ's reincarnation. Speaking of such, Oz will continue to be Oz and shed guidance and light upon the group(s) and bring them further into the loop, and possibly, completely manifest in his reincarnation. Qrow will continue to have his internal conflicts as well as external conflicts, primarily with Raven. Yang HOPEFULLY will lean towards accepting the lore of Remnant and harness her Semblance to become a powerhouse in battle. There's no telling how her relationship with her mother will go, so its really hard to say. Blake will loop the rest of her team into her family's plan(s) for the Fang and continue to purge from her shell. Weiss, well Weiss will be Weiss, and continue to be Weiss. Her powers are going to continue to develop and she will be a key element in Team RWBY in this upcoming volume. Nora and Ren are minor characters and will most likely continue to provide support for those characters who have yet to develop completely. Sun will most likely join the group as the independent freelancer, OR be adopted in the JNR family as their fourth member instead of Oscar, as mentioned above.
