Why there are no Cross-Realm raids… yet.
Let me preface this with what Blizzard’s viewpoints are on this. Bornakk - Doing this is a bit more complicated than the 5 player dungeons. For 5 player dungeons it’s not a big deal to allow the random heroics to skip lock
WoW Hotfixes for December 15th, 2009
Seems these are wonderfully (or annoyingly) common.  This time, they’re half reversing the drop rate change to the Battered Hilt.  Now, those of you that want a sparkly new sword like mine can more likely get it.  In addition, Quel’Delar is now Unique-equipped.  That didn’t make sense to me, because the questline is not repeatable (supposedly).  So, in theory, you should never have a second one that would conflict with the first one in the first place.  But I digress. Among the other changes, is that you can now complete the “Perfect Run” of Naxxramas in any order you choose.  Maybe I missed something here, but couldn’t you do that before?  Probably a bug with doing the immortal run Saph/K’T first. Blizzard is squashing bugs left and right.
Guide to the new Icecrown 5-mans
The final assault on the Lich King has begun and its up to you to secure victory for the forces of the Ashen Verdict. Sylvannas (or Jaina if youre one of THOSE people) leads you on a action-packed journey to Arthas’ guest house. The Icecrown Citadel 5-man dungeons are the toughest challenges you’ll find outside a raid, and it doesnt disappoint. The new heroics push every bit of your skill and if you survive… well… good luck in the raid. You’re ready for it. WoW.com gives us a look at the questline and dungeons that make up the stealth recon assault into the back halls of the citadel.
Blizzard confirms: 3.3 is due today – Fall of the Lich King!
Fall of the Lich King, the latest World of Warcraft content update, is coming!

Now the time has come to break through the fortified gates of Icecrown Citadel and confront the Lich King in the frozen heart of his domain. Follow Jaina Proudmoore or Sylvanas Windrunner through the Forge of Souls, Pit of Saron, and Halls of Reflection in an attempt to subvert the Lich King’s army in a new multi-wing 5-player dungeon. Join the Ashen Verdict as they charge through the citadel’s main gate to take on the Scourge’s most powerful leaders and fearsome monstrosities in a new 10- and 25-player raid.

Amazing guide to WoW 3.3 patch
WoW.com has an amazing guide to the WoW 3.3 patch.  Below is a table of contents of sorts with links leading to some amazing, if not highly speculatory, information about the 3.3 patch.  Also, the 3.3 patch is rumored to be launching in approx. 1 week! Patch 3.3 is the final major content patch for World of Warcraft: Wrath of the Lich King. Three new 5 man dungeons and a new 10/25 man raid will be introduced at Icecrown Citadel, along with a ton of other changes to the game.
New Info About Shadowmourne
The guys over at MMO-Champion have done an update on the new legendary item from the 3.3 PTR.  Check out the super-sweet proc effects on the video.  Remember its geared towards 2-handed DPSers, so all of you hunters are out of luck.  And in addition it’ll be a couple months after 3.3 hits the live servers before we’ll see any of these floating around Dalaran, thanks to Blizzard’s wonderful idea of gating out the individual sections of the Icecrown Citadel.  Enjoy the show. Shadowmourne – Legendary Axe The end of the PTR is near and it’s time for a new preview of
Hearthstone to… Tarren Mill?
The upcoming 3.3 is introducing Kirin Tor rings which have the ability to teleport your character back to Dalaran every 30 minutes. This means that, with the ring, you no longer have to tie your hearthstone to Lagaran, err I mean, Dalaran. 
Blizzard explains some upcoming changes in 3.3
Blizzard is teasing us once again with reasonings behind balance changes, tank shortages, and general upcoming updates in 3.3 and Cataclysm. Kirin’ Tor Rings in 3.3 Item level 251 versions are currently planned for patch 3.3. I’m not sure what the cost to upgrade is but it will probably be similar to previous upgrades. We are only upgrading the existing ring types, not providing a new one, so that means no tank version. (Source) Tank Shortage The “shortage” is caused by a lot of people not wanting to tank or not spending the time to gear up and tank – and if they don’t want to gear up at all then they probably don’t want to tank anyway or maybe don’t want to spend the time learning it. I still think the new Dungeon System will help with this through the faster turnover rate and random heroic feature, but overall we can’t force people to play something they don’t want to play so there will likely always be a shortage of tanks or healers to some degree.
