WotC has published the results of last month's psionics survey. They indicate a generally positive reaction to the playtest psionics rules, with some aspects proving less popular, especially the way psionics and magic interact, and the mystic class itself getting lower scores. The general conclusion is that more work is needed on the psionics rules, and that there will be another draft in a couple of months.
