Are all the Legionaries Catchable?

"Catch all 722 pokemon" Is that still the plan?

All pokemon up to gen 6, including legendaries and megas, as well as deltas, will be available for you to obtain in the next and last version, 1.2. I think I heard somewhere that they will probably not add gen 7 pokemon to Insurgence. Though Zygarde 50% is gen 6, Zygarde Cell, Zygarde 10% and Complete Zygarde are all gen 7, so they will most likely not be in the game.
