soon is a rather subjective word 
This could mean days, weeks,… Are you guys doing weekly releases, monthly releases, releases on the fly,…? If it is weeks, then I will follow the GitHub build suggestion.
I have been developing now without being able to enter VR mode as I do not want to uninstall/install the correct version when playing with Oculus games vs developing games with UE4.
Possible UE4 feature request: to be able to develop against a specific runtime of Oculus Rift other that the installed version on the machine. Otherwise any new update of the Oculus software will always result in not being able to enter VR mode in UE4.
