I think they had said that the story arcs that they'll be doing will follow any of the RvB characters created up to this point (and possibly some new ones), and will take place at any time in the RvB universe. Maybe like 007nightfire said with the rampage of the Meta, or maybe Felix and Locus in the UNSC.
