FA CUP 3rd round tie V MK Dons query

Seeing as tickets are not yet on sale and the club can't really know the interest in numbers wanting tickets for the tie , Is there a logical reason why there are just the two stands open for this fixture ? also if at a later date the club decide to open the north and south stands will fans that purchased tickets for the east and west be able to move to the north or south stands .

Thankyou .

Thanks for the feedback, but we feel the West and East Lower sections of the ground will be sufficient to cope with the demand for this fixture. Given the additional operating cost of opening additional sections of the stadium, this makes economic sense. It isn't our expectation that we will need open additional sections, but should that be the case, we would open the south stand next, as that stand will already be partially open to house the visiting fans.
