Ninja Castle = Neo Tokyo?

There's more proof then you have for SEA's version. The best way to make a guess at what will happen in the future is the past. It's a fact proven in history and behavoirs of people for as long as time has existed. We have gotten what CMS' Zipangu as so far. There's a greater chance of getting the CMS Kaede then SEA Kaede.

You lack proof either, you're going by patterns which is pure post hoc fallacy.
