Veraedge as light controls with Savant - is this sustainable?

I have a Savant HA system for A/V and use Veraedge for light control - about 74 nodes. VeraEdge works really well. With so much invested in z-wave switches am I at risk of VeraEdge going obsolete? What recommendations do folks have?

Why would there be any risk ? There are many other vendors available that will control any of your zwave devices for you.
In fact, I think SAVANT these days have a native ZWAVE hub/controller that would integrate with the rest of their gear basically consolidating both your A/V and light-control with SAVANT.
