A member of the trade press, formerly at the Linux Foundation, has speculated at length as to the release date of a CentOS 6. I and at least one other member of the CentOS core group were approached for comment on this topic, coming into the US Thanksgiving holiday. We were discussing how to respond, but we had not issued a formal reply. That writer went to press with a piece that expresses a date not of any formal CentOS origin or estimate. His words, his choice, his opinion, and nothing more
Here is a statement which is perhaps more accurate:
CentOS really doesn't do pre-release interviews as to release dates and process, other than what anyone may read in and infer from the 'centos-devel' mailing list. Any CentOS 6 series will ship when it is ready and will be available when it is announced
CentOS is the successor in part by merger of Tao Linux ('Hi, David'). This quote comes from the Tao
