I highly doubt they have any worries at all - Wallabies Rugby Challenge and All Blacks Rugby Challenge it doesn't get much better than that in the brand development committee weekly meeting.
Never said they should be worried, but the official game of the Rugby world cup being held in New Zealand and not featuring any New Zealand players probably wasn't what they had planned when they went exclusive.
Financially it won't make much difference to them anyway, if people don't know who the All Blacks and Wallabies are I doubt a game will change that and suddenly make them want to buy tickets and merchandise
