I will be very surprised of they choose kites. Those designed for upwind/downwind racing are in the same boat as formula boards, which means that in winds below 8 knots, it's almost impossible to achieve much if any upwind performance.
Formula boards can plane in 6 knots if you have a 12.5m sail and pump your brains out, but upwind performance is essentially not there. I don't know the planing threshold for kites, but I doubt it's any better then the formula boards. If the kites get stuck in dying winds, someone has to bring them in or they can body drag in for an hour if there is enough wind to keep the kite in the air.
Too many issue with launching, light winds, beach space, courses way off shore, etc. to go with kites in my opinion.
