HTC today provided clarity on the cost of purchasing all the necessary hardware (minus a PC) to use its Vive Pro headset. For anyone who is not upgrading from the original Vive and therefore doesn't already own touch controllers and base stations, HTC will offer a starter kit bundle for $1,099, beginning April 5.

The starter kit pairs the upgraded Vive Pro headset with two Vive 1.0 controllers and two 1.0 base stations, neither of which are included with the $799 headset. Purchased as a bundle, you're essentially paying $300 the base stations and controllers. If purchased separately, they would run about $530.
