Support for Z-Wave 700 Controllers

Hi

Are there any news regarding Z-Wave 700/800?
Currently I have a “Razberry” (Z-Wave 500). But if this will die in future, maybe there are no old controllers to buy anymore. Already at this time it seem to be harder to get an old one. So I’m a little bit afraid and hope there will be support soon, because I plan to invest even more in Z-Wave devices.
