I like that they don't push things out too frequently. Back in the day, every White Dwarf issue had a 1-2 page Chapter Approved section with Errata, clarifications, and FAQs. It was a complete nightmare for all the players to keep current on, and since it was written by different studio members it could be wildly inconsistent. I would appreciate a standard release schedule though. If they released FAQ updates, for example, every 6 months on a specific date, then the nets would at least know when to expect changes.
Having said that, I don't think the Studio is letting anyone hang, I just think they are isolated from the community. They probably finished with the Chaos Codex months ago and are currently playtesting the next 2 or 3, using the Chaos Codex RAI, because they are a close-knit group that would come up with a consensus on what is in there, and probably don't have WAAC or rules lawyers in their group.
