Looks like 1/7 Alter Fate is ready for preorder. 
The total height of it is approximately 35cm including the base. The riot blades are 27cm long and the riot zeus zamber is approximately 56cm. That is a very long blade. And as you can see from the image, the blade has an extra stand to support it. =/
And it seems to be more costly than the Alter Hayate… This figurine is priced at 12,800 yen (Exclude tax) or rather 13,400 yen (Includes tax).
