Ah, but it is. When Spiderman 2 broke all records in film history, Marvel decided that Spidey is their new poster boy, bumpping Wolvy down to 2nd place. We STILL haven't seen a resession of Spidey toys since Spidey 2.
I think part of the reason also, is Marvel. They're... cheap. They have lost contact with their buyers on all levles, as Civil War has proved. They have no ideas, they want to do things as cheaply as possible. Spiderman and Wolvy are always big sellers, therefore, push them.
I agree about 14/15 making or breaking the line.
