There's a two month event called Convergence that Septembers' Booster Gold one shot was leading into. Basically the baddie he was dealing with is mucking with time and capturing different timelines. Flashpoint, Kingdom Come, Tangent, Charlton, DC pre-new 52 and a couple others. The boys show up in these solicits which will conclude the next month. We have:
Blue Beetle starring Ted Kord. JLI Booster Gold with double the Booster and Rip Hunter finally turning up.
