I agree, it's probably like that. They are not stupid, they know how the leaks with the early shipping of discs and review copies are well guarded.Now that you mention The Catalyst, I got a promo CD with a sticker that says "Embargoed until 7.30pn on 2nd August 2010"
I'm done with the puzzles, it sucks that you can't solve the old ones anymore. Couldn't finish #5, had to leave home, I come back and #6 is already up, that blows.
