I just finished listening to the Radd Titan interview (
https://www.youtube.com/watch?v=aKL1BLDEtws) with Kinetiquettes and near the end (starting at 2:33) they dropped that info. Mai Shiranui, 1/4, and diorama. That's potentially too much of a good thing.
They did say from the SNK license and mentioned King of Fighters. I'm not familiar with all of her team stages in King of Fighters but my immediate thought was of her Fatal Fury original stage at the temple on the water.
Their Thundercats diorama is huge and that's 1/5 scale. Mai diorama at 1/4 will be crazy. I can't wait to see it.
