If I'm not mistaken, no BlazBlue character has ever been cut from the roster completely at any point in the series. Nu-13 was replaced by Lambda-11 between CT and CS and back again for CP, but essentially they play in the same way (with subtle difference I think but this is excusable due to patches and updates which would have had the same effect on Nu-13)

Besides, what a new and unique way for ASW to screw people out of their main characters if they removed a character. Honestly, I believe that Mu-12 being brought back for Chrono Phantasma was a bit of a deus-ex-machina just to keep her in the game after her origin in Continuum Shift. If they can do that, then I see no reason Izayoi will be cut.
