5. Kang
6. Count Nefaria
7. Psylocke

9. Wasp
10. Dr. Octopus

That's given rumors that Beast and Dr. Strange are coming soon, otherwise they would have made the list...

Any Young Avengers
Any Runaway
Blink
Any Generation X

Falcon
Jack of Hearts
Stingray
Bug
Rom and the Spaceknights
Whirlwind
She-Hulk
Vulture from the 1990s Spider-Man series(i'd love to shed my 10" figure of him)
Tigra
Hercules

Assuming the rumors are true and we're to get Doc Strange and X-23 my new list (1-10) goes:
Ares, Emma Frost, Rogue, Blackbolt, Invisible Woman, Abomination, Psylocke, Hercules, Scarlet Witch, Nova.

Top ten in no particular order though:
Graviton, Kang, Rogue, Abomination, She Hulk, Baron Zemo, Baron Strucker, Skurge the Excutioner, The Leader, and Elektra/Black Cat tie. Yes, most are villains but even with the increase in villains lately we still are way off villain to hero ratio.

oh, and has anyone mentioned:
Captain Marvel 2 (Monica Rambeau)
?

1. Gambit (comic accurate! mold/build similar to series 3 Cyclops)
"Death variant"

2. Rogue (no bush wack hair)
"Modern-ish variant"

3. Magneto (no shrimp mold with removable helmet)

4. Daredevil (no shrimp mold with holster for clubs) Bullseye (no shrimp mold with alternate maskless head) comic pack?

5. Elektra (with removable bandana) Psylocke (like Daredevil and Bullseye I find both to be very similar and we all know how Hasbro likes to do things =)

6. White Queen/Goblin Queen (same as above)
"Diamond variant"

7. Mr. Sinister (with alternate head)

8. Omega Red (see pic for a astonishing comic pack =)

9. Beyonder (with attachable armor)

10. M.O.D.O.K.

Nice selection man, some unique choices you got there!

Maybe a Magneto Cyclops?
Kinpin
Shadowland Daredevil
Maria Hill
She-Hulk
Invisible Woman

BETA RAY BILL

Giant Classic Titanium Man

I would kill to see a full box set of Great Lakes Avengers.
Barring that, at least give me a Squirrel Girl.

Mephisto
Venom
Black cat
Mysterio
Adam Warlock
Elektra
Kraven the Hunter
Domino
Psylocke
Emma Frost

I don't remember doing this, prolly did, but, eh, here's a "new" or first list.

1 Baron Zemo (II)
2 Kang
3 Onslaught
4 Nate Grey
5 Mr Sinister
6 Sharon Carter, Mario Hill and Victoria Hand 3-pack (kinda cheating, but eh)
7 The Hood
8 Machinesmith
9 Madame Masque
10 Madelyne Pyror

Ok...this is a really hard one. There are so many figures I'd like to see. But my top 10 would probably be:

1. Professor X
2. Scarlet Witch
3. Doc Oc
4. Kingpin
5. Beast (classic furry version with variant for cat version)
6. Rogue (Jim Lee)
7. Emma Frost
8. Mephisto (they will never do this...they can't even bring themselves to put "bleeding edge" on an Iron Man figure much less make a figure of the devil...but it would be awesome)
9. Firelord
10. Super Skrull

Runners up would include Terrax, Mr. Sinister, Kang, Vulture, Drax the Destroyer and the Beyonder.

Cool comic packs would be Blackbolt & Medusa (War of Kings), Nova & Air Walker (From a Silver Surfer comic), and Gamora & Pip the Troll (from an Infinity Watch comic).

A great gigantic battles would be Uatu the Watcher with a "What If..." comic.

This is a weird list, but here you go:
1. Cosmic Carnage (Silver Surfer and Symbiote)
2. Doppelganger Spiderman
3. Man-Thing
4. Beta Ray Bill
5. Mr. Sinister
6. Demogoblin
7. Bishop
8. Sauron
9. Deathlok
10. Carrion

You know, I just had to add a few others, to add some taste to my list:

Morph
Forge
MU Gambit (with decent accessories)
Professor X
Pestilence

We need more villians- my assembled heroes mob the villians like five to one (though the villians are waaay tougher overall).

Jason Abbadon's list (drumroll please):

Terrax
Annihilius (variant with Quasar's Quantum Bands)
Adam Magus (to go with the upcoming Adam Warlock, of course)
Super Skrull (a sometimes hero, sometimes villian)
Phalanx Ultron
Nimrod (classic)
High Evolutionary
Quasar
Nova
She Hulk (with FF costume variant)

No particular order...

Carnage
Beast
The Fury
Jigsaw
Yellow Jacket II
Dormammu
Footkiller
Anti Venom
Wolverine vs S.H.I.V.A. Gigantic Battle
