They are not looking to replace Xen. They plan to add support of KVM without breaking Xen: https://github.com/QubesOS/qubes-issues/issues/7051#issuecom...

They also plan to replace Fedora in dom0 with something minimized https://github.com/QubesOS/qubes-issues/issues/1919#issuecom.... Is this a problem for you?
