It’s designed to eliminate Wi-Fi dead spots in the home, but only one of the units will be a smart things hub, and it has exactly the same range as the current SmartThings hub, so in terms of the discussion in this thread, it doesn’t change anything at all.
There are several discussions in the forum already about the new router, so if you’re interested just look for one of those.

In fact at present, the new one has somewhat less functionality than the existing SmartThings hub, as not all of the same devices will work with it, although they are trying to get them all supported.
