A few people have already asked us for a non-Wrath RSS feed, and we're working on asking our tech guys if that's possible (it's very possible to get RSS feeds of any of our categories by adding "rss.xml" to the end of any of our Category listings, but it's not so easy to get a feed if everything but a certain category), and we're doing as much as we can to keep major spoiler information behind the breaks and out of sight if possible. But the information's out there, and just like the Burning Crusade beta, odds are that you'll have heard a little bit about what's happening in Northrend if you read any WoW sites at all.
The good news, of course, is that Blizzard always keeps a few aces up their sleeve -- even if you drowned yourself in the latest and greatest Wrath leaks and information, it's a guarantee that you'll find at least something in the live version of Northrend that you didn't hear about before. But until then, just how much do you want to know? Are you planning on playing the beta nonstop in the hopes that you do so much you don't have to buy the actual game, or are you keeping ears and eyes closed for the next few months in hopes that you'll enter a completely new and unfamiliar world whenever you install the next expansion?
