What sticks out in my mind is, whatever the changes in the announcement are, there are two possibilities (based on the time constraints from the initial knee-jerk announcement to now):
The changes are a simple monetary increase across the board and will be implemented immediately/in the next few days
The changes are more structural and complex (e.g. adding places to PB payout)so will be implemented in the next few months)
If they go with number 1 - there should be no issue, its just a number change in coding.
If number 2 - then oh fuck me....its going to be a disaster if they have the same IT gang.
