I freaked when I heard Winter in the new episode. So as it stands, the likelihood is that Cinder's old team included Summer Rose and Winter Schnee, The problem then being that there's now a pretty big age gap between Weiss and her sister. Still plausible.

It's also possible that these characters were not on a team together, but have some other connection. I don't think this is as likely to be the case though.
