I think they'll be more, "Steal Pokemon to conduct horrible experiments, then take over the world," type.
So you want them to do stuff like Team Plasma did to Genesect?
Well, considering this game is probably about genetics, I could picture them manipulating Pokemon genetics to try and induce evolution. Team Rocket tried it, but were somewhat unsuccessful. Maybe after a few years and letting technology develop, this new team got Pokemon evolution manipulation down so well that they can induce evolution in Pokemon previously unable to.
