I was curious, so I looked it up. The on-line retail price is marked down to $899 from an original list price of $1599. Whew! It would be a bummer to have been one of the first people to buy one. It's sort of weight integrated. The description says that there are two weight pockets. You just can't release the weights.

"JoeDiver and Dacor present the H.U.B! The latest innovation and the worlds first integrated diving system come from a company that for 45 years has been on the forefront of the industry.
The HUB eliminates the risk of diver entanglement. Thanks to its front mounted regulator and fully integrated hoses, the HUB insures greater safety, helps safeguard the environment and provides a more streamlined profile, thus enhancing diving comfort and minimizing air consumption.
The Inflator unit is always within reach. With its ultra-practical positioning, the HUB inflator is always at hand to provide perfect buoyancy control by means of its 2 oversized inflation and deflation buttons.
The Safe Second (octo) is always at hand too! It is stowed in a special compartment, there is no trailing hose which might become entangled during the dive, and its forward position maximizes freedom of movement when the alternative second stage is in use.
The HUB is super easy to set up to dive and also incorporates two rear pockets for non-releasable weights, allowing you to customize the buoyancy of the unit and reduce the number of weights on the belt."
