Preview panel time – I am just going to do bullet points might clean up later. Hit the jump for my bullet point blitz:

- Deathwing is the main bad dude behind Cataclysm
- Deathwings eruption into the world is what is the cause of the cataclysm.
- both new races will have extensive lore and quest explaining how they fall into these factions!
- Goblin mounts look like a hot rod!!!
- heroic deadmines and shadiwfang keep!!!!
- Worgen look sweet!
- More new class and race info in the class panel.
- 7 new zones – completly new zones that have not been opened before! This includes: mount hyjul, twilight highlands, deepholm, uldum, gilneas, the list isle, sunken city of vash’ji
- All old world zones will be getting a revamp!
- Guild advancement system. More on that later. (guild talents?!?)
- New secondary profession: Archaeology – leads to path of the titans progression
- No new talents :(
- Path of the titans – you pick a Titan to follow and this unlocks customization.
- Mastery system – works with the talent trees – so more points in a tree gives you mastery in that tree with special percs.
- You can fly everywhere!
- 5 new leveling zones, 2 starting zones 1-15, new zone flows for leveling, 5 levels per zone.
- some of these zones look completely different!
- Sunken city and Mount Hyjul will be starting zones and will lead to deepholm (which will be cataclysms dragonblight)
- Sunken city is an under water zone.
- underwater mounts
- I hope there is a finding nemo quest.
- Deepholm, not part of Azeroth, you enter it via the hole that Deathwing created when he broke into the world.
- Uldum just west of Tanaris, this is an egyption inspired zone – fabled land of the Titans.
- Mount Hyjal, ragnoros is trying to take over this place. Malfurion Stormrage will be here trying to protect the world tree!
- Twilight highlands, this is where deathwing lands in grim batol. New port towns and red dragon bases.
- Ton of new dungeons and raids. The firelands, Uldum 2 level up dungeons, Blackrock caverns, grim batol (level up and raid) and skywall same as grim batol. And again Heroic Deadmines and Shadowfang Keep!!!!
- PvP news – island zone of Tol Barad will be like wintergrasp but will also be a pvp daily quest hub. Battle for Gilneas battlground. Unconfirmed number of new arena maps. Rated battlegrounds to be similar to the arena rated system.

And that’s the preview complete – I suppose I should tidy this up later.

UPDATE – blizzard have put up the Cataclysm site – check it out
