Support for RHEL 8 or CentOS 8?

Released in May of 2019, when is support for these 2 OS's happening?

CentOS 7 & RHEL 7 become unsupported in 4.5 years and that's the latest you support. Makes things very difficult when we build new machines that are expected to go 5 years out.

For those that have tried. The RHEL 7 agent installs on 8 but can't be loaded into the new 4.18+ kernels.
