Meh.
No patents, no technical specs, and they profile three team members: the hardware guy, the UI guy, and a guy whose job is to “inject fun into the company.” 
Other than the magical marketing statement that “this will make everything work together” (with no technical specs to back that up), it’s not clear what advantage this would have over any competition, such as google home and Amazon echo combined with a tablet dashboard. (Yes, that would be two devices instead of one, but hardly anyone cares about that.)
EchoSistant can already turn an echo into an intercom, although the technical set up is complicated.
Nucleus is an Alexa enabled video intercom so it gives you voice control of anything Alexa controls. And you can buy it now.

Admittedly, it’s not also a dashboard, so it just comes down to what you want.
There are already good existing dashboards for SmartThings, but they don’t also run voice. But again they’re available now.
For example, ActionTiles:
I’m not saying it would be a bad idea to have a dashboard combined with a voice assistant, I’m just saying I don’t see any evidence that Fuse is going to be the best option in that category.
I’ll take a look at Fuse once it’s actually shipping, but there’s nothing there to motivate me to back it early.
