[CentOS] RHEL 8 speculation ???

Is there any blog that has information on a potential RHEL 8 release date?

boost in 7 is now too old for some things, in addition to gcc. There are 
solutions in 7 to those issues but it's starting to feel like 6 felt 
shortly before 7 came out, so I wonder if it is getting near to time.

I'm working on a major project bitcoin related and it would be 
frustrating to deploy a bunch of CentOS 7 virtual machines only to have 
8 come out fairly soon afterwards.
