There are psi-armors planned, yeah, but they will have different functions than Mind Control. The Mind Control line will be concluded by an upgrade to Witch Armor which will also have the Rod build-in, and will probably allow you to fly since the Star Gods are doing it.
There will be 3 general categories of new psi: first, high-energy psi, pyrokinesis, that sort of stuff; probably least interesting since you have weapons to do that. Second, speed/stun psi, basically advancing along the line of Blitz/Crystalisk/Seductress armors; Third, endurance psi, dependant on Reticulans, which will be the best counter to Star Gods' powers, but it will force you to sacrifice speed & reactions, and will have weakness to melee.
