Our intentions are to start small with a release called Phrenic Shards in which we explore how some choose to meld their internal phrenic potential into "shards", metaphysical manifestations. An example is the Weapon Shard, a malleable piece of phrenic energy capable of becoming nearly any kind of weapon.
If the first few releases are successful, we'll likely turn towards exploring more 4E ideas. Feel free to look around the forums, where we discuss potential future releases.
I'll also note that we're not making rules for "psionics", but the Phrenic power source. Seems we're not excluded from creating our own power sources, which is a nice saving grace.
