OpenManage Essentials - End of Life / Support date?

I haven't been able to find any documented dated for when Dell OpenManage Essentials (OME) will go end of life or end of support.  With OpenManage Enterprise now being the focus, and Essentials noting that they will no longer support newer devices or receive any functionality updates, it is just a matter of time.  

Does anyone have this date?  I'm in the private sector, and to help provide justification for moving to something newer (i.e. OpenManage Enterprise) it is always a slam dunk for us if we can say "such and such product will stop being supported on this date".
