All Super7 Ultimates figures are made to order, they basically only make as much as ordered and they aren't made for general retail. The long time between preorders and release is to let them schedule and arrange production of the required number of figures. This is not uncommon among collector lines, especially those that aren't made to be sold at K-Mart and the like. Here is another example of a company that does the same thing: https://www.goodsmile.info/en/products/announced/2021
GSC also takes preorders for products many months in advance to gauge the size of their production runs. Pulling up a specific example, this figure went up for preorder last month but won't be released until Jan 2023, assuming no possible delays: https://www.goodsmile.info/en/produc...e+Beleren.html
Super7's preorder model is pretty normal and there is no need to get worked up about it.
