I really can't comprehend why they would do this. Hello Kitty's store is almost always completely empty from my experience, and now there's talks of it getting a full land replacing one of the most profitable areas in the resort that was JUST redone? I don't buy it at all.
The only way I could see it working is if Springfield is replaced by a Japan-themed area that just so happens to use Hello Kitty prominently. That would make thematic sense for Studios (next to other major cities like New York and London), would be a perfect fit aside SNW, and be a more sensible and potentially profitable replacement for Springfield. But Springfield being replaced by a full HK land? I don't buy it at all.
