Yeah, you seem to be jumping to the conclusion that this is immediately Tamashiis fault, It won't be. Nin Nin likely hasnt ordered enough or not of the right Anakin and Tamashii told them they couldn't supply anymore of the early bonus figure.
Like Lipsmack already said, web ex's can't be ordered in bulk, they have to be ordered per person and paid for right there and then hence why you can't preorder without paying for web ex's. Tamashii wouldn't accept the order then not meet supply and demand, they have very strict rules on that.
Every company has exclusive figures, Tamashii is no different. You can't expect them to make every figure equal when it's obvious some won't sell as well as others. Web ex's are Tamashiis damage control. It's either Tamashii takes a risk with limited runs or they simply don't make them, that's the choice here.
We all know the prequels aren't very well liked and that translates to merch aswell. Imo the only guaranteed sellers from that trilogy are ep3 Obi and Anakin, and Maul who is already out.
