I'm ashamed to say that I hadn't noticed the year, only the month, on the blog post. One of my fellow admins pointed it out, but… that's the most recent we have, so I've let it stand. lol. D'oh. It may be a little bit before someone can update that, but I'm adding some links to a few specific comments in this thread for tracking, so hopefully I can poke you when there is an update :)

(And I've only been here a couple of months as an admin, so I only know some rough numbers - I think the costs are generally not that different, but I can't swear to anything)
