They have two feasts (!) and a mage table down, and are apparently waiting on the hunter to get back from being afk, since the rest are jumping around or sitting....and one guy is dancing.

They are in the guild <Wrynn's Raiders>. Here's a full raid list (from left to right, based on the first pic):
Dwarf Hunter: Garl Grimgrizzle + Bubbles <Hunter's Pet> (he's an engineer; he has the goggles - he also has an <Away> flag)
Human Paladin: Danric (he's dancing with crusader aura up; he looks to be ret, based on the tiny mana pool)
Worgen Death Knight: Dethbringer (it's already been brought! by Deth'tilac)
Human Priest: Peach (she's holy; she has chakra: sanctuary up...and keeps casting it repeatedly - also jumps occasionally)
Worgen Warlock: Victoria + Guz'tul <Warlock's Pet> (she's just sitting patiently with her imp)
Gnome Mage: Raena (she jumps quite often; can't tell whether she's arcane or fire, since she only has molten armor up)
Draenei Shaman: Aoewyn (she's resto; sitting and spamming water shield - love the play on AoE and Eowyn for her name)
Gnome Rogue: Cuddles (he's only wielding one sword, which is odd; jumps quite often - love his name)
Human Warrior: Tolv the Impatient (one of the tanks; looks very grumpy - just standing and staring at the raid)
Night Elf Druid: Astrylian (the other tank; standing at the ready, facing the trash)
And here's the horde group!
They are in the guild <Thrall's Thrashers> and spawned in the same location as the alliance raid. Their gear, placement, and movements are all duplicates of the alliance raid.
Blood Elf Hunter: Johnny Awesome + Dazzle <Hunter's Pet> (it amuses me so much that he leveled his engineering)
Tauren Paladin: Brighthoof (he alone is worth the visit due to the cow + bright yellow gear; he also has crusader aura up)
Orc Death Knight: Deathok (he actually flexes on occasion; I didn't see the worgen do that)
Troll Priest: Wish (also holy; it's kinda funny)
Blood Elf Warlock: Incinderella + Kazdum (her name is just pure awesome)
Undead Mage: Quincy (seems to bounce around a bit less than his gnomish counterpart)
Orc Shaman: Nezra (also resto)
Undead Rogue: Stabu (another win name - I was slightly surprised she turned out to be female!)
Goblin Warrior: Snizzle (seems a lot more patient than his alliance counterpart)
Tauren Druid: Hunaka Greenhoof (actually saw her take a stutter step forward toward the mobs
