This is excellent news. After the long lead times for 6.0 and 6.1 its very reassuring that CentOS seems to have gotten its momentum back and is tracking the Red Hat releases with minimal lag.
Did you try the mailing lists for example? (linked from the main page): http://centos.org/modules/tinycontent/index.php?id=16
Definitely didn't want to talk about build processes, just lots of handwaving about how hard it is to get right. I even recall he eventually pointed out some "build scripts" under pressure, neglecting to mention that they weren't actually usable by anyone without hidden knowledge and package requirements he didn't want to talk about.
The whole thing left a very bad taste in my mouth.
