I've traveled and shot with Jeff and he has the 1DX3 as well as the R5 and R6 so he has the option of taking any of those bodies with him to the games. Canon USA has fully supported him at the games with equipment and loaners as well but Canon USA is NOT going to be there this time so don't know how that will work because none of the tech guys he works with will be there. Looking forward to his review and feedback about the R3
