Apparently they've "at least one top secret project for Atari" somehow crammed into the pipeline. This is another "reach beyond" the traditional MMORPG.
"Cryptic Studios is working on at least one top secret project for Atari. … Like Neverwinter, our Top Secret work represents our continued commitment to diversify and reach beyond the boundaries of traditional MMORPG gaming," reads Cryptic's product page.
This is of course "in addition to developing Neverwinter and supporting both Champions Online and Star Trek Online with new content," so they're busy bees alright. The studio is looking for new hires to bolster their workforce - quite understandable.
