A lot of those girls have not been officially confirmed. Some of the names were taken off the board that Jasmine signed at her press event today, but that board was already shown to have errors with the casting. It was printed before final selection of some of those girls could have possibly been cut.
Edit: It's likely that most of the girls listed will walk since they're regulars anyways, but I would take that list with a grain of salt. This is my own list from BZ with only girls that had been confirmed by themselves or someone reputable.
