What models and/or weapons options are still missing from the armies that have a hardback codex?
And I'm talking about GW models, 3rd party doesn't count.

I'll start with the armies I have.

Eldar
Farseer on jetbike
Farseer with Witchblade (you could just use the one with the staff...but still)
Warlock on jetbike

Howling Banshee Exarch w/Triskele
Warp Spider Exarch w/Spinneret Rifle
Warp Spider Exarch without powerblades

Space Marines
I don't have many SM, so please help me complete this list.

Dreadnought Multi-Melta (how the heck have they not made this?! Forgeworld does have one)
