According to Bryan Alvarez, the current plan for the John Cena/Nexus storyline is to pattern it after the Ted DiBiase/Virgil storyline from the early 1990’s. The idea is that Wade Barrett will continue ordering Cena around until the point where Cena finally snaps and attacks Barrett. It appears that the creative team has an idea for the end of the storyline, but the rest of it will be done week-by-week.
