What gateways/modems is Shaw using for its 250 Mbps service?

Here in Toronto Rogers has recently introduced this service. They are using the Hitron 3GN gateway and tons of people are having problems with the device. I see that Shaw how has a 250 Mbps service. So what hardware is Shaw using for their 250Mbps service? This seems to require a 24x8 DOCSIS 3.0 gateway/modem and there aren't too many of those available yet.
