Absolutely. It may, but that is not what has been stated.
isx's communication to date have stated that all interactions have been positive, it is moving forward and final preparations have been put in place including fees.
it's probably not worth worrying about. I can't say definately that it will happen. But, I have absolutely no concerns. Additionally it will only improve the costs to aus operation, and allow for high risk transaction post big 4 fully moving away.
so it is important but isx have restated thier guidance regardless of a delay in cost improvement. Thats almost an upgrade to guidance in itself.
