RNJR, Qrow, and Oscar are in Mistral. Weiss is on an airship headed there and will thus likely get there in the first couple episodes to meet with Winter. Yang is on her bike to there and will likely also get there in the first couple episodes (though after Weiss because planes are faster than motorcycles). Blake is going to get there the last of them because 1) she hasn't started heading there yet and 2) she's going to thwart Adam's attack, which is likely the central conflict of the next volume and thus will be saved for the last couple episodes (though I expect her to get there earlier, just not to meet anyone soon.)  Yang will meet with RNJR/Qrow/Oscar because Ruby likely will have mailed her the address of where they're all staying. Winter and Weiss will investigate the criminal underworld of Mistral (as Winter has been doing) and that's likely how they will meet with Blake, who knows why the shady behavior is happening. And once Adam's attack happens, like the heroic people they are, everyone will respond to the evil efforts and they happen to find each other there. So it will be disjointed at the beginning, but by the end of V5 the characters will definitely be back together.

The more we see, the more it looks like a chess match to me.
