They do 1-3 figures for most licenses anyway...
When Iron Man, Predator and Batman get 10 or many more in some cases...
2 from Tron Legacy
2 from Sucker Punch
2 from Blade
1 from Avatar
1 from Clash of the Titans
1 from Expendables
1 from Wolverine
& others not springing to mind
...is just not enough for those fans, not when some great figures like Clu, Sweat Pea, Nomak, Neytiri, Dolph Lundgren, a Bone Clawed Wolverine & others don't see the light of day.
I want a Magneto, Beast, Azazel, Mystique, Xavier & Emma Frost minimum, yet HT will probably only make Magneto and Xavier
Same with Sucker Punch they're doing 2/5 so far, 3 more would complete the line-up of main characters yet they likely won't bother but they will remake more Batman and Iron Man characters that have already been made.
