First - I think we're looking at 2 more weeks until Patch 3.2 hit's the servers. I base this on a couple of unrelated events, which when taken together, point towards a larger picture.
1) The final bosses are hitting the PTR tonight.
2) Blizzcon is in four weeks - IMO they either want to get it out 2 weeks early, or wait until the week after Blizzcon.
3) Some small last minute tweaks are coming in, and GC will want to address them at Blizzcon.
4) I have a nose for trouble, and this smells like trouble.
I could be off, but I'd be surprised if they wait until Blizzcon to release 3.2. I know Blizzard stands by the "we'll release when it's ready" position, but I'd bet on this.
By all that's holy, please don't put Goblins in the game. I hate gnomes. I especially hate gnome tanks. Goblins would be just as bad. I really hate their animations...ugh. Worgen would be pretty cool I suppose, but you'd have a host of people swarming to reroll worgen on Alliance. I certainly don't think that they will be neutral or have the ability to choose Alliance/Horde at will (or via quests). PvP would be hell if you can't recognize the enemy until they are close enough to see their health bar.
Jazz hands are still a dream of mine though - need to keep running H MGT so I can have them for a few minutes at a time until the Horde/Alliance switch opens up. I'm still torn between male/female though. It's a shame you can't run through all the animations at lvl 1.
Here's hoping for an incredible fragment drop rate tonight.
