I would make fury the favourite, Wilder is impressively powerful and determined but fury is very good at bending the rules in fights and great at roughing people up, I think his leaning and pushing will wear Wilder down pretty quick, there is around a 25lb weight difference between the too.. Wilder is really not that great either someone with a good jab will scramble his brain pretty easy. So for me fury wears him down and stops him then gets blown up by joshua.
Of course Wilder could one punch KO him too.. He does have amazing power.
I also think fury will pull out of the fight a month before once he sees how little him and Wilder sells in America.
