Incorrect Blizzcon Predictions For 2010

Blizzcon is coming up in just over a week, so time to put predictions that are usually proven wrong to electronic paper is running out.  Here are my best guesses for this year's event.

• Diablo III and the first SC2 expansion (called the second game in a "trilogy" so that Bobby Kotick can charge the new game price instead of the expansion price) will be playable.  I really am not following either game at this point, so there's not much else I can predict about them. 
• Cataclysm's cinematic introduction will make its debut.  My guess is that it will finally include gnomes, though I suppose we can't put it entirely past Blizzard to make a point of including Goblins and Worgen over gnomes as a running gag. 
• With most of the juicy Cataclysm news out on live servers, PTR's, and the no-NDA beta, WoW news will include discussion of patch 4.1.  The patch will include a major feature that has not been announced or discussed publicly (sorry, dance studio). 
• Blizzard will have to announce the mystery fourth project (confirmed to be an MMO based on a new IP) if they do not want the event to be widely viewed as a disappointment.  My guess is that the new game will be more action-based, will be designed with some form of item shop or other transaction system in mind, and will not be a straight up fantasy setting (perhaps Steampunk, Sci-Fi or Cyberpunk). 
• Date MMO-Champion leaks the juicy details: Monday, Oct 18th.

We'll see how much of a laugh we have over this post sometime next week.
