I think Diamond Select and Art Asylum should release an exclusive X-Men Origins : Wolverine pack similar to what they did for Iron Man. I would expect the following :
John Wraith
Scott Summers with removable sunglasses and "optic blast " head
Weapon XI with "optic blast" head
Gambit with staff and "charged" cards accessories
I think this proposed set would be highly desired among the fans. And I think some of the already developed X-Men Origins : Wolverine minimates were a little unnecessary such as a Deadpool* minimate whose debatable movie counterpart, Weapon XI has more screen time and a Video game inspired shirtless Wolverine.
Please leave feedback on what you would want to see possibly developed.
* This Deadpool doesn't resemble Ryan Reynolds
