I fail to see how moving to a rolling release strategy results in any kind of "death", seems like FUD to me. Rolling release, trying to stick to upstream releases as closely as possible, works well with Arch Linux, I'm glad CentOS learned from Arch Linux success. DISCLAMER: I'm not even a CentOS user, but I just like what RH does and has done for "the Linux community" as you call it (I would just call it "society" but whatever).
