It's not just the approvals. That's just why giving updates is pointless. And as I was trying to show...for all we know it's still waiting on the guys from marvel to approve the box art, or the suit, or whatever. (Not the issues as I have heard, but just an exapmle)
There's a lot more issues with this then most human figures. Those ones that came out in months where repaints of old heads or just a head and weapon. This still has an entirely new head, though it's not a human face it still requires the same work load. It has a unique one off suit. And the kicker is the stingers/back pack.
And how to get it both engineered for mass production and assembly...and packaged. Then to the customer with a standard failure rate not a high one. It's a pretty tricky design. One that is prone to breaking. If the failure rate is (which results in returns, refunds and replacements) say 25% then the figure is a loss.
This figure is way more complex for production and engineering then Cap and Thor and Visin and SW and QS and thanos and hulk and a majority of figures. Up with ultron and iron man. And they have had 10 years to work out the engineering basics with iron man and still the mk45 will have taken close to 2 years by the time it arrives.
If you go back a page or two I have an update on what I heard was the issue with this. And remember, there's only so much time to go around. They can't work on everything all at once. If a figure falls out if it's production window them it's usually placed in a Que for work at a later time or in free time. Or they risk missing production Windows on every figure after it. Better to have one or two outliers then screw up 20 figures.
