Agree with Ron that new CloudStack users are unlikely to want to use
RHEL/CentOS v6.x, however as Eric hinted at there will be existing CloudStack
users using version 6 for a while still.
I am working with one company with 1000+ RHEL6 KVM hosts and no easy (or
particularly clean) RHEL7 upgrade path – for them dropping RHEL6 support in
2018 would be a major issue.
On the management side this should however be a lot less of an issue.

It might also be helpful to know what version of ACS as well.
Some indication of your plan/desire to upgrade ACS, hypervisor, or
management server operating system might be helpful.
There is a big difference between the situation where someone is running
ACS 4.9x on CentOS 6 and wants to upgrade to ACS 4.12 while keeping
CentOS 6 and another environment where the planned upgrade to ACS4.12
will be done at the same time as an upgrade to CentOS 7.x.
Is it fair to say that any proposed changes in this area will occur in
4.12 at the earliest and will not likely occur before summer 2018?

Same deal with the version of MySQL that it comes with.

2020. New versions of Cloudstack with new features not supported by Centos 6
(such as LVM support for KVM, which requires the LIO storage stack) can require
Centos 7 or later, but the last Cloudstack version that supports Centos 6.x as
its server host should continue to receive bug fixes until Centos 6.x is EOL.
