The specs are listed on the Kickstarter page now.
Technical specs of the Dev Kit (subject to change)
Head tracking: 6 degrees of freedom (DOF) ultra low latency
Field of view: 110 degrees diagonal / 90 degrees horizontal
Resolution: 1280x800 (640x800 per eye)

Not exactly high resolution (considering the wide FOV), but not bad either
Seems like an oversight that they've left out the specs
