So I happened to listen to The Instance #168 this morning (thanks Scott and Randy for entertaining me during this morning at work), and I couldn't help but grin as they joked about the new bag you can get from Haris Pilton in the World's End Tavern in Shattrath City: the Portable Hole. You can see a picture and all on MMO-Champion (as always your best source of wow information).
Ok if you're not an old Dungeons & Dragons geek you won't understand and probably laugh at the "Hole" part. But for all old table roleplayers like me, the portable hole is the best bag you can carry as a dungeon adventurer since the middle 70s.
Just another tribute of the folk at Blizzard to this ancestor of rpgs that is Dungeons & Dragons.
