Well if you saw the new movie trailer you'lld see that Team Rocket was there. It makes no sense because in the episode Unova's Survival Crisis Team Rocket goes back to Kanto. Why are they in the trailer?
Team Rocket return to Isshu/ Unova in BW110. It just hasn't been dubbed/ aired in the US yet. You have to remember that the anime hasn't finished yet, and the Genesect movie isn't due for release until July.
